A type of chemical reaction in which oxidation and reduction occurs is called a redox reaction, which stands for reduction-oxidation. This is why sodium is stored in kerosene so that it does not come in contact with moisture or oxygen. For example, Sodium reacts vigorously with water and oxygen and gives a large amount of heat in the process. For example, one of the highly reactive non-metals is phosphorus and it catches fire when exposed to air that is why it is stored in water to prevent its contact with atmospheric oxygen. That is, they will react with aqueous acids to form solutions of salts and water; for example, CoO + 2H 3 O + → Co 2+ + 3H 2 O. When oxygen reacts with most metals a metal oxide is formed where oxygen has an oxidation state of -2. For example, with careful control of oxygen, the oxide M 2 O (where M represents any alkali metal) can be formed with any of the alkali metals. For example, (ii)They form negative ions and are good oxidising agents. The oxidation of a metal by oxygen gas could then be explained as the metal atom losing electrons to form the cation (being oxidized) with the oxygen molecule gaining electrons to form oxygen anions. The metal initially has a charge since it is bonded to oxygen. Answer: (i) Reaction with oxygen: Non-metals react with oxygen to form acidic oxides. But how reactive a metal seems to be depends on how fast the reaction happens - not the overall amount of heat evolved. Metals, on being burnt in air, react with the oxygen to form metal oxides. Type of chemical reaction. Non-metals react with oxygen to form non-metal oxides. On the whole, the metals burn in oxygen to form a simple metal oxide. Electronic Concept of Oxidation Reduction.
