Which one of the elements with the following outer orbital configuration may exhibit the larger number of oxidation states ?

A

`3d^(5) 4s^1`

B

`3d^(5) 4s^2`

C

`3d^(2) 4s^2`

D

`3d^(3) 4s^2`

Text Solution

Verified by Experts

The correct Answer is:
B
Number of oxidation states = Number of valence electrons. Since number of valence electrons is maximum in `3d^(5)4s^2` , it shows maximum number of oxidation states.
