Explanation:
Detailed explanation-1: -Fe metal represents more than one oxidation state because it belongs to transition series.
Detailed explanation-2: -when V is in its +2 oxidation state, it becomes stable since the s orbital has no electrons in it whereas when it is in the +3 oxidation state, it loses another electron maybe from the d prbital. And hence V^+2 is more stable than V^+3.
