Answer:

It gains electrons, reducing its overall charge

Explanation:

When an ion of element gains electrons its overall charge decreases, thus the it reduced.

Consider the half equation involving Iron (III) ions.

Fe³⁺+ e⁻ → Fe²⁺

In this equation, the iron III ion has gained an electron changing then to iron II ions. The charge has thus decreased from 3+ to 2+.

This is a reduction reaction.
