The tendency of an electrode to lose electrons is known as
1 Electrode potential
2 Reduction potential
3 Oxidation potential
4 e.m.f.
Explanation:
(c) The magnitude of the electrode potential of a metal is a measure of its relative tendency to lose or gain electrons. i.e., it is a measure of the relative tendency to undergo oxidation (loss of electrons) or reduction (gain of electrons). \(M \to {M^{n + }} + n{e^ - }\) (oxidation potential) \({M^{n + }} + n{e^ - } \to M\) (reduction potential)
