Answer: Iron gains electrons mean It is reduced

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Zn\rightarrow Zn^{2+}+2e^-

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Fe^{2+}+2e^-\rightarrow Fe

Thus iron gains electrons mean It is reduced
