Detailed explanation-1: -What is the oxidation-reduction process? It oxidizes the material that gives electrons. It forms a chemical called rust when iron reacts with oxygen because it has been oxidized (the iron has lost some electrons) and the oxygen has been reduced (the oxygen has gained some electrons).

Detailed explanation-2: -Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen. Reduction is the gain of electrons, loss of oxygen or gain of hydrogen.

Detailed explanation-3: -Oxidation is the loss of electrons, or you can also think of it as the gaining of a positive charge. Reduction is the gain of electrons or the gaining of a negative charge.
