The metal that shows highest and maximum number of oxidation state is:

(A)Fe
(B)Mn✓ Correct
(C)Ti
(D)Co

Answer: (B)

Solution

In the 3d series manganese has the electron configuration allowing it to use all its 3d and 4s electrons, so it exhibits the highest oxidation state (

+ 7

, as in

Mn O_{4}^{-}

) and the maximum number of oxidation states. Hence Mn.
