2 Na2O (s) 4K (s) + + O2 (g) —>2 K20 (s) Lithium (and to some extent sodium) form simple oxides, X2O, which contain the common O2- ion. WARNING!This reaction is EXTREMELY violent and dangerous! Sodium sulfite react with oxygen 2Na 2 SO 3 + O 2 → 2Na 2 SO 4 [ Check the balance ] Sodium sulfite react with oxygen to produce sodium sulfate. Oxygen removal is incomplete when the sulfite to oxygen ratio is leas than the stoichiometric quantity. Lithium's reactions are often rather like those of the Group 2 metals. The sulfite/oxygen reaction is inhibited by chelants, by contaminants in the feed water, or by treatment chemicals. For example, lithium oxide reacts with water to give a colourless solution of lithium hydroxide. questions on the reactions of Group 1 metals with oxygen and chlorine, © Jim Clark 2005 (modified February 2015). How many grams of Na2O are produced when 93.7 g of Na reacts? . Sodium burns in air with often little more than an orange glow. 2.If you have 15.0 g of Na, how many grams of O2 are required for the reaction? Now imagine bringing a small positive ion close to the peroxide ion. 4Na(s)+O2(g)→2Na2O(s) 1. It is soft enough to be cut with a knife. Our summaries and analyses are written by experts, and your questions are answered by real teachers. More specifically, it's called oxidation-reduction. Sodium (and to some extent potassium) form peroxides, X2O2, containing the more complicated O22- ion (discussed below). The equations are the same as the equivalent potassium one. Solubility of sodium and sodium compounds If the temperature increases (as it inevitably will unless the peroxide is added to water very, very, very slowly! The rubidium doesn't show a clear flame colour in this video, although the caesium does show traces of blue-violet. What is the difference between saturated, unsaturated, and supersaturated? this reaction can become a problem as pressures go up, so the use of sulfite is limited to lower pressure installations. These are simple basic oxides, reacting with water to give the metal hydroxide. A solution containing a salt and hydrogen peroxide is formed together with oxygen gas. Finely divided nickel can burn, forming nickel(II) oxide, NiO. 2. The reaction can be very violent overall. In the presence of sufficient oxygen, they produce the compound whose formation gives out most energy. The equation for the formation of the simple oxide is just like the lithium one. Sodium - Sodium - Chemical properties: Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). eNotes.com will help you with any book or any question. You can use the freeze /thaw method to remove dissolved oxygen from a solution. That gives the most stable compound. One major web source describes rubidium superoxide as being dark brown on one page and orange on another! Below are more examples of balanced chemical equations showing state symbols. Write the chemical equation and name the reaction when a solution of sodium chloride is mixed with a solution of silver nitrate and a white precipitate of silver chloride is formed. Unlike the reaction of oxygen with sulfite or hydrazine, the hydroquinone reaction is quite complex and appears to go forward in more than one stage. In each case, there is a white solid residue which is the simple chloride, XCl. Magnesium. This is included on this page because of the similarity in appearance between the reactions of the Group 1 metals with chlorine and with oxygen. You will need to use the BACK BUTTON on your browser to come back here afterwards. As long as you have enough oxygen, forming the peroxide releases more energy per mole of metal than forming the simple oxide. 2 Ni (s) + O 2 (g) 2 NiO (s) Reaction of nickel with ammonia. We say that the positive ion polarises the negative ion. The more complicated ions aren't stable in the presence of a small positive ion. Na 2 O 2 is a Sodium is a silvery-white metal with a waxy appearance. Another potentially violent reaction! You get a white solid mixture of sodium oxide and sodium peroxide. The hydrogen peroxide will again decompose to give water and oxygen as the temperature rises. 2 Na(s) + O 2 (g) Na 2 O 2 (s) Compounds such as Na 2 O 2 that are unusually rich in oxygen are called peroxides. In the video both look black! Why are different oxides formed as you go down the Group? A page showing Balanced Chemical Equations for The reactions between Sodium and Oxygen, Aluminium and Chlorine, Aluminium and Oxygen, Calcium and Chlorine, Magnesium and Bromine. The surface is bright and shiny when first cut, but quickly becomes dull as sodium reacts with oxygen in the air. There is nothing in any way complicated about these reactions! It is, anyway, less reactive than the rest of the Group.). If you have 17.6 g of Na, how many grams of O2 are required for reaction? Violent! Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. This is then well on the way to forming a simple oxide ion if the right-hand oxygen atom (as drawn below) breaks off. Reactions with water. In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor. Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. If the reaction is done ice cold (and the temperature controlled so that it doesn't rise even though these reactions are strongly exothermic), a solution of the metal hydroxide and hydrogen peroxide is formed. Reaction between sodium metal and pure oxygen initiated by some water. sodium + oxygen → sodium oxide 4Na (s) + O2(g) → 2Na2O (s) The reactivity of the group 1 elements increases down the group, so their reactions with oxygen get more vigorous. asked Oct 17, 2017 in Class X Science by aditya23 ( -2,145 points) These are all very reactive metals and have to be stored out of contact with air to prevent their oxidation. Lithium is unique in the Group because it also reacts with the nitrogen in the air to form lithium nitride (again, see below). Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. gcsescience.com 22 gcsescience.com. Both superoxides are described in most sources as being either orange or yellow. The covalent bond between the two oxygen atoms is relatively weak. The equation for the overall reaction is: An oxidation-reduction reaction can be written as two half reactions, one showing oxidation and one showing reduction: The two half reactions are multiplied by coefficients, if necessary, to arrive at the same number of electrons in each half reaction. How many mole (s) of oxygen gas (O … The tubes are broken open when the metal is used. this only works for the metals in the lower half of the Group where the metal ions are big and have a low charge density. BUT . Small pieces of sodium burn in air with often little more than an orange glow. Depending on how far down the Group you are, different kinds of oxide are formed when the metals burn (details below). A thin film of sodium oxide (Na 2 O) forms that hides the metal itself. Use the BACK button on your browser to return to this page from either of these links. Sodium reacts with oxygen as. If this is the first set of questions you have done, please read the introductory page before you start. This page mainly looks at the reactions of the Group 1 elements (lithium, sodium, potassium, rubidium and caesium) with oxygen - including the simple reactions of the various kinds of oxides formed. Sodium reacts with oxygen to form sodium oxide and has the following balanced chemical equation: 4 Na + O 2 --> 2 Na2O. 3. It is a matter of energetics. sodium+oxygen gas=sodium oxide balanced symbol equation-4 Na + O2 = 2 Na2O The reaction rate of sodium sulfite was studied as a function of oxygen concentration, Na/sub 2/SO/sub 3//O/sub 2/ ratio, temperature, catalyst, pH and surface/volume ratio.The reaction rate of hydrazine with dissolved oxygen was also studied. Similarities Between Photosynthesis And Cellular Respiration. It also deals very briefly with the reactions of the elements with chlorine. The amount of heat evolved per mole of rubidium in forming its various oxides is: The values for the various potassium oxides show exactly the same trends. The superoxide ions are even more easily pulled apart, and these are only stable in the presence of the big ions towards the bottom of the Group. Lithium, sodium and potassium are stored in oil. There is more about these oxides later on. Larger pieces of potassium burn with a lilac flame. Reaction with oxygen is just a more dramatic version of the reaction with air. Sodium, for example, burns with an intense orange flame in chlorine in exactly the same way that it does in pure oxygen. ), the hydrogen peroxide produced decomposes into water and oxygen. There is a diagonal relationship between lithium and magnesium. The equation for the formation of the simple oxide is … The resulting solution is basic because of the dissolved … They are stored either in a vacuum or in an inert atmosphere of, say, argon. Hydrogen gas released during the burning process reacts strongly with oxygen in the air. So why do any of the metals form the more complicated oxides? The reaction between sodium and oxygen is called oxidation because electrons are transferred from one atom to another. Small pieces of sodium burn in air with a faint orange glow.

This page describes the reactions of the Period 3 elements from sodium to argon with water, oxygen and chlorine. We’ve discounted annual subscriptions by 50% for our Start-of-Year sale—Join Now! You will find this discussed on the page about electronegativity. Sodium and potassium metal are stored under kerosene oil to prevent their reaction with the oxygen,moisture and carbon dioxide of air.They are so reactive that they react vigorously with oxygen.They catch fire and start burning when kept open in the air. The two must occur together because an atom can't lose electrons without another atom to accept them. Click hereto get an answer to your question ️ Write equation for the reaction of : (a) Sodium with oxygen(b) Magnesium with oxygen Potassium, rubidium and caesium form superoxides, XO2. Oxidation is the loss of electrons and reduction is the gain of electrons. You get a white solid mixture of sodium oxide and sodium peroxide. Other major commercial applications of sodium chloride include its use in the manufacture of chlorine and sodium hydroxide by electrolytic decomposition and in the production of sodium carbonate (Na 2 CO 3) by the Solvay process.The electrolysis of aqueous sodium chloride produces sodium hypochlorite, NaOCl, a compound of sodium, oxygen, and chlorine used in large quantities in … For example, sodium oxide will react with dilute hydrochloric acid to give colourless sodium chloride solution and water. The reaction between sodium and oxygen is called oxidation because electrons are transferred from one atom to another. Sodium thiosulfate acts as an oxygen scavenger (Gupta and Carman, 2010a). This is the best way to get rid of oxygen. When sodium reacts with oxygen each sodium atom loses an electron, which means sodium is oxidized, and each oxygen gains two electrons, meaning it's reduced. The concentration of O2 is a linear function of the decay rate. Potassium (lilac) burns most vigorously followed by sodium (orange-yellow) and then lithium (red), as you might expect. Already a member? Forming the superoxide releases even more. As you go down the Group to sodium and potassium the positive ions get bigger and they don't have so much effect on the peroxide ion. Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. . More specifically, it's … Again violent! How many grams of O2 are 2Na(s) + O 2 (g) → 2Na 2 O 2 (s) 4Na(s) + O 2 (g) → 2Na 2 O(s) Reaction of sodium with water. I assume the same thing to be true of the caesium oxides, although I couldn't find all the figures to be able to check it. Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. Consider the peroxide ion, for example. The formula for a superoxide always looks wrong! These simple oxides all react with an acid to give a salt and water. Sodium. REACTIONS OF THE GROUP 1 ELEMENTS WITH OXYGEN AND CHLORINE. Users of sodium sulfite often express concern with its slow and incomplete solubility. Sodium has a very exothermic reaction with cold water producing hydrogen and a colourless solution of sodium hydroxide. Sodium hydroxide may react with oxygen to form sodium peroxide. Lithium is the only element in this Group to form a nitride in this way. Sodium. This time, a solution of the metal hydroxide and hydrogen peroxide is formed, but oxygen gas is given off as well. For the record, it also reacts with the nitrogen in the air to give lithium nitride. Hydroquinone reacts with dissolved oxygen in an aqueous system. 3.How many grams of O2 are needed in a reaction … Sodium metal is heated and may ignite and burn with a characteristic orange flame. The equation for the formation of the peroxide is just like the sodium one above: The formula for a peroxide doesn't look too stange, because most people are familiar with the similar formula for hydrogen peroxide. Sodium reacts with oxygen to form sodium oxide and has the following balanced chemical equation: {eq}\rm 4Na + O_2 \to 2Na_2O {/eq}. Oxygen removal is incomplete when the sulfite to oxygen ratio is leas than the stoichiometric quantity. Magnesium has a very slight reaction with cold water, but burns in steam. These reactions are even more exothermic than the ones with water. Atomic Structure. Rubidium and caesium are normally stored in sealed glass tubes to prevent air getting at them. The reaction rate is a function of temperatures, solution pH, and the ratio of hydroquinone to dissolved oxygen present in the system. - I have no idea what is going on here! Sodium, however, reacts with O 2 under normal conditions to form a compound that contains twice as much oxygen. A solution containing a salt and hydrogen peroxide is formed. They are then added together, canceling out electrons and producing the equation for the overall reaction. With pure oxygen, the flame would simply be more intense. The reaction produces a white solid mixture of sodium oxide and sodium peroxide. A number of sodium compounds do not react as strongly with water, but are strongly water soluble. The equation for the formation of the simple oxide is … Sign up now, Latest answer posted May 09, 2016 at 2:26:02 PM, Latest answer posted February 21, 2016 at 1:54:19 AM, Latest answer posted July 22, 2013 at 3:57:27 AM, Latest answer posted June 23, 2016 at 11:43:58 PM, Latest answer posted August 02, 2016 at 4:25:48 PM. There is a bit of video from the Royal Society of Chemistry showing the two metals burning on exposure to air. Both metals catch fire in air and produce superoxides, RbO2 and CsO2. Sodium reacts with oxygen to produce sodium oxide. Once again, these are strongly exothermic reactions and the heat produced will inevitably decompose the hydrogen peroxide to water and more oxygen. Electrons in the peroxide ion will be strongly attracted towards the positive ion. Using larger amounts of sodium or burning it in pure oxygen produces a strong orange flame. Sodium bisulfite is a common industrial reducing agent, as it readily reacts with dissolved oxygen: 2 NaHSO 3 + O 2 → 2 NaHSO 4 It is usually added to large piping systems to prevent oxidative corrosion. The equation for the formation of the simple oxide is just like the lithium one. Even though it only has one charge, the lithium ion at the top of the Group is so small and has such a high charge density that any peroxide ion near it falls to pieces to give an oxide and oxygen. Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H 2). This is an exothermic reaction. 4 Na (s) + O 2 (g) → 2Na 2 O(s) At the top of the Group, the small ions with a higher charge density tend to polarise the more complicated oxide ions to the point of destruction. Forming the more complicated oxides from the metals releases more energy and makes the system more energetically stable. The reaction rate of sodium sulfite was studied as a function of oxygen concentration, Na/sub 2/SO/sub 3//O/sub 2/ ratio, temperature, catalyst, pH and surface/volume ratio.The reaction rate of hydrazine with dissolved oxygen was also studied. 4Na(s)+O2(g)â 2Na2O(s) 1. Realizing ©2021 eNotes.com, Inc. All Rights Reserved. If sodium is burnt in air the result is white sodium peroxide, Na 2 O 2, together with some sodium oxide, Na 2 O, which is also white. A white solid mixture of sodium oxide and sodium peroxide is formed. Start your 48-hour free trial and unlock all the summaries, Q&A, and analyses you need to get better grades now. What are ten examples of solutions that you might find in your home? The rest also behave the same in both gases. Small pieces of potassium heated in air tend to just melt and turn instantly into a mixture of potassium peroxide and potassium superoxide without any flame being seen. The hydrogen peroxide will decompose to give water and oxygen if the temperature rises - again, it is almost impossible to avoid this. (Lithium in fact floats on the oil, but there will be enough oil coating it to give it some protection. A homemade instrument for the measurement of oxygen concentration in aqueous solutions measures the decay rate of the phosphorescence of a Pd-porphyrin complex (phosphor) dissolved in the solution, which is flashed every 0.1 s with 630 nm light. When any substance burns in oxygen it is called a combustion reaction. The structure of the superoxide ion, O2-, is too difficult to discuss at this level, needing a good knowledge of molecular orbital theory to make sense of it. Small pieces of sodium burn in air with often little more than an orange glow. Its chemistry is well explored. 4NaOH + O2 = Na2O2 + 2H2O This works best if the positive ion is small and highly charged - if it has a high charge density. It reacts with oxygen in the air to give white lithium oxide. Are you a teacher? The peroxide equation is: Potassium The conditions necessary for the effective reaction of sodium erythorbate with oxygen are called “activation”. How many grams of Na2O are produced when 62.5g of Na reacts? Lithium burns with a strongly red-tinged flame if heated in air. Who are the experts?Our certified Educators are real professors, teachers, and scholars who use their academic expertise to tackle your toughest questions. What are 5 pure elements that can be found in your home? The Reactions of the elements with Chlorine. The prefix per- means "above normal" or "excessive." Sodium reacts with oxygen to produce sodium oxide. Oxygen scavengers are reducing agents in that they remove dissolved oxygen from water by reducing molecular oxygen to compounds in which oxygen appears in the lower, i.e., -2 oxidation state. 4Na (s) + O2 (g) —>2 Na2O (s) 4K (s) + + O2 (g) —>2 K20 (s) Lithium (and to some extent sodium) form simple oxides, X2O, which contain the common O2- ion. WARNING!This reaction is EXTREMELY violent and dangerous! Sodium sulfite react with oxygen 2Na 2 SO 3 + O 2 → 2Na 2 SO 4 [ Check the balance ] Sodium sulfite react with oxygen to produce sodium sulfate. Oxygen removal is incomplete when the sulfite to oxygen ratio is leas than the stoichiometric quantity. Lithium's reactions are often rather like those of the Group 2 metals. The sulfite/oxygen reaction is inhibited by chelants, by contaminants in the feed water, or by treatment chemicals. For example, lithium oxide reacts with water to give a colourless solution of lithium hydroxide. questions on the reactions of Group 1 metals with oxygen and chlorine, © Jim Clark 2005 (modified February 2015). How many grams of Na2O are produced when 93.7 g of Na reacts? . Sodium burns in air with often little more than an orange glow. 2.If you have 15.0 g of Na, how many grams of O2 are required for the reaction? Now imagine bringing a small positive ion close to the peroxide ion. 4Na(s)+O2(g)→2Na2O(s) 1. It is soft enough to be cut with a knife. Our summaries and analyses are written by experts, and your questions are answered by real teachers. More specifically, it's called oxidation-reduction. Sodium (and to some extent potassium) form peroxides, X2O2, containing the more complicated O22- ion (discussed below). The equations are the same as the equivalent potassium one. Solubility of sodium and sodium compounds If the temperature increases (as it inevitably will unless the peroxide is added to water very, very, very slowly! The rubidium doesn't show a clear flame colour in this video, although the caesium does show traces of blue-violet. What is the difference between saturated, unsaturated, and supersaturated? this reaction can become a problem as pressures go up, so the use of sulfite is limited to lower pressure installations. These are simple basic oxides, reacting with water to give the metal hydroxide. A solution containing a salt and hydrogen peroxide is formed together with oxygen gas. Finely divided nickel can burn, forming nickel(II) oxide, NiO. 2. The reaction can be very violent overall. In the presence of sufficient oxygen, they produce the compound whose formation gives out most energy. The equation for the formation of the simple oxide is just like the lithium one. Sodium - Sodium - Chemical properties: Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). eNotes.com will help you with any book or any question. You can use the freeze /thaw method to remove dissolved oxygen from a solution. That gives the most stable compound. One major web source describes rubidium superoxide as being dark brown on one page and orange on another! Below are more examples of balanced chemical equations showing state symbols. Write the chemical equation and name the reaction when a solution of sodium chloride is mixed with a solution of silver nitrate and a white precipitate of silver chloride is formed. Unlike the reaction of oxygen with sulfite or hydrazine, the hydroquinone reaction is quite complex and appears to go forward in more than one stage. In each case, there is a white solid residue which is the simple chloride, XCl. Magnesium. This is included on this page because of the similarity in appearance between the reactions of the Group 1 metals with chlorine and with oxygen. You will need to use the BACK BUTTON on your browser to come back here afterwards. As long as you have enough oxygen, forming the peroxide releases more energy per mole of metal than forming the simple oxide. 2 Ni (s) + O 2 (g) 2 NiO (s) Reaction of nickel with ammonia. We say that the positive ion polarises the negative ion. The more complicated ions aren't stable in the presence of a small positive ion. Na 2 O 2 is a Sodium is a silvery-white metal with a waxy appearance. Another potentially violent reaction! You get a white solid mixture of sodium oxide and sodium peroxide. The hydrogen peroxide will again decompose to give water and oxygen as the temperature rises. 2 Na(s) + O 2 (g) Na 2 O 2 (s) Compounds such as Na 2 O 2 that are unusually rich in oxygen are called peroxides. In the video both look black! Why are different oxides formed as you go down the Group? A page showing Balanced Chemical Equations for The reactions between Sodium and Oxygen, Aluminium and Chlorine, Aluminium and Oxygen, Calcium and Chlorine, Magnesium and Bromine. The surface is bright and shiny when first cut, but quickly becomes dull as sodium reacts with oxygen in the air. There is nothing in any way complicated about these reactions! It is, anyway, less reactive than the rest of the Group.). If you have 17.6 g of Na, how many grams of O2 are required for reaction? Violent! Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. This is then well on the way to forming a simple oxide ion if the right-hand oxygen atom (as drawn below) breaks off. Reactions with water. In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor. Sodium is ordinarily quite reactive with air, and the reactivity is a function of the relative humidity, or water-vapour content of the air. If the reaction is done ice cold (and the temperature controlled so that it doesn't rise even though these reactions are strongly exothermic), a solution of the metal hydroxide and hydrogen peroxide is formed. Reaction between sodium metal and pure oxygen initiated by some water. sodium + oxygen → sodium oxide 4Na (s) + O2(g) → 2Na2O (s) The reactivity of the group 1 elements increases down the group, so their reactions with oxygen get more vigorous. asked Oct 17, 2017 in Class X Science by aditya23 ( -2,145 points) These are all very reactive metals and have to be stored out of contact with air to prevent their oxidation. Lithium is unique in the Group because it also reacts with the nitrogen in the air to form lithium nitride (again, see below). Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. gcsescience.com 22 gcsescience.com. Both superoxides are described in most sources as being either orange or yellow. The covalent bond between the two oxygen atoms is relatively weak. The equation for the overall reaction is: An oxidation-reduction reaction can be written as two half reactions, one showing oxidation and one showing reduction: The two half reactions are multiplied by coefficients, if necessary, to arrive at the same number of electrons in each half reaction. How many mole (s) of oxygen gas (O … The tubes are broken open when the metal is used. this only works for the metals in the lower half of the Group where the metal ions are big and have a low charge density. BUT . Small pieces of sodium burn in air with often little more than an orange glow. Depending on how far down the Group you are, different kinds of oxide are formed when the metals burn (details below). A thin film of sodium oxide (Na 2 O) forms that hides the metal itself. Use the BACK button on your browser to return to this page from either of these links. Sodium reacts with oxygen as. If this is the first set of questions you have done, please read the introductory page before you start. This page mainly looks at the reactions of the Group 1 elements (lithium, sodium, potassium, rubidium and caesium) with oxygen - including the simple reactions of the various kinds of oxides formed. Sodium reacts with oxygen to form sodium oxide and has the following balanced chemical equation: 4 Na + O 2 --> 2 Na2O. 3. It is a matter of energetics. sodium+oxygen gas=sodium oxide balanced symbol equation-4 Na + O2 = 2 Na2O The reaction rate of sodium sulfite was studied as a function of oxygen concentration, Na/sub 2/SO/sub 3//O/sub 2/ ratio, temperature, catalyst, pH and surface/volume ratio.The reaction rate of hydrazine with dissolved oxygen was also studied. Similarities Between Photosynthesis And Cellular Respiration. It also deals very briefly with the reactions of the elements with chlorine. The amount of heat evolved per mole of rubidium in forming its various oxides is: The values for the various potassium oxides show exactly the same trends. The superoxide ions are even more easily pulled apart, and these are only stable in the presence of the big ions towards the bottom of the Group. Lithium, sodium and potassium are stored in oil. There is more about these oxides later on. Larger pieces of potassium burn with a lilac flame. Reaction with oxygen is just a more dramatic version of the reaction with air. Sodium, for example, burns with an intense orange flame in chlorine in exactly the same way that it does in pure oxygen. ), the hydrogen peroxide produced decomposes into water and oxygen. There is a diagonal relationship between lithium and magnesium. The equation for the formation of the simple oxide is … The resulting solution is basic because of the dissolved … They are stored either in a vacuum or in an inert atmosphere of, say, argon. Hydrogen gas released during the burning process reacts strongly with oxygen in the air. So why do any of the metals form the more complicated oxides? The reaction between sodium and oxygen is called oxidation because electrons are transferred from one atom to another. Small pieces of sodium burn in air with a faint orange glow. Out of sodium and sulfur, sodium is a metal. Reactivity increases as you go down the Group. Again, these reactions are even more exothermic than the ones with water.
