Question 3(multiple choice worth 4 points) (04.04 lc) what does it mean when an element is reduced? it empties a valance shell, reducing its atomic radius. it gains electrons, reducing its overall charge. it increases electronegativity, reducing its ability to bond. it loses electrons, reducing its electron number.

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.
