Chromium has the electronic configuration `4s^1 3d^5` rather than `4s^2 3d^4` because

A

4s and 3d have the same energy

B

4s has a higher energy than 3d

C

`4s^1` is more stable than `4S^2`

D

`4s^1 3d^5` half-filled is more stable than `4s^2 3d^4`

Text Solution

Verified by Experts

The correct Answer is:
D
Cr has `[Ar]4s^1 3d^5` electronic configuration because half filled orbital are more stable than other orbitals.
