Webreduction, any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased. The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized. See oxidation-reduction reaction. WebRedox reactions. Oxidation is the loss of electrons by a reactant. When a metal element is reacting to form a compound then it is being oxidised. The metal atoms are losing electrons to form an ...
