The electronic configuration of an element is `1s^(2)2s^(2)2p^(6)3s^(2)3p^(4)3d^(5)4s^(1)` .This represents its

Options

A. Excited state
B. Ground state
C. Cationic form
D. Anionic form

Answer

B

Explanation

`_(24)Cr= 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3s^(2)3d^(5)4s^(2)`
This is the ground state electronic configuration for chromium .There is only one electron in the `4s` orbital because `d^(5)` is a more stable half-filled configuration Reason for the stablity of the half -filled and fully filled orbitals are symetry and excharge energy
