NO2, nitrite, versus NO3, nitrate.

Explanation:

For both ions the negative charge is delocalized. The oxidation state of nitrogen in nitrite ion is +III; the oxidation state of nitrogen in nitrate is +V.

Nitrate ion is in fact a potent oxidant, but this potential is often masked in aqueous solution.
