Detailed explanation-1: -The gain of electrons is called reduction. Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox reactions.

Detailed explanation-2: -In oxidation/reduction reactions, there is a transfer of charge-an electron-from one species to another. Oxidation is the loss of electrons and reduction is a gain in electrons.

Detailed explanation-3: -The gain of the electrons is known as reduction, whereas the loss of electrons is known as oxidation.

Detailed explanation-4: -Oxidation–reduction reactions, commonly known as redox reactions, are reactions that involve the transfer of electrons from one species to another. The species that loses electrons is said to be oxidized, while the species that gains electrons is said to be reduced.

Detailed explanation-5: -Hence, the gaining of electrons is known as reduction.
