Excited state configuration of `Mn^(2+)` is

Options

A. `t_(2g) ^(4)`
B. `t_(2g)^(3) e_(g)^(2)`
C. `t_(2g)^(4)e_(g)^(2)`
D. `t_(2g)^(5)e_(g)^(0)`

Answer

B

Explanation

Electronic configuration of `Mn ^(2+) ` is ` [Ar] 3d^(5)`
According state of `mn^(2+)` ion three electrons go in `e_(g) ` level `(d_(z^(2))and d_(x^(2)-y^(2))).`
