# What are atoms that gain electrons and have a negative charge?

$\text{Oxidizing agents..............}$

#### Explanation:

Oxygen and fluorine are excellent oxidizing agents and tend to gain electrons...........i.e.

$\frac{1}{2} {F}_{2} + {e}^{-} \rightarrow {F}^{-}$

$\frac{1}{2} {O}_{2} + 2 {e}^{-} \rightarrow {O}^{2 -}$

Because both of these species lie to the right of the Period as we face the Table, they have a large (unshielded) nuclear charge that explains their tendency to oxidize.
