Why is thay when a metal reacts with a non metal ,the reaction is always a redox reaction

Answer»

If an atom loses electrons then it is OXIDIZED and if an atom gains electrons it is reduced.So, When a metal and non - metal react, there is an ICONIC bond formed, which means 1 loses electron while the other gains them. So,since this REACTION involves the exchange of electrons, so it is TERMED as a redox reaction.
