Which of the 3d-seres of the transition metals exhibits the leagest number of oxidation states ?

A

Cr

B

Mn

C

Fe

D

Co

Text Solution

Verified by Experts

The correct Answer is:
B
Mn shows the widest range of oxidation states of all the elements form `(-3)` to `(+8)`, because its electronic configuration is `3d^(5)` `4s^(2)` and hence it has maximum number of valence electrons to involved in bonding.
