Chromium has the electronic configuration 4s13d5 rather than 4s23d4 because

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

A
4s and 3d have the same energy
B
4s has a higher energy than 3d
C
$4 s^{1}$ is more stable than $4 s^{2}$
D
$4 s^{1} 3 d^{5}$ half-filled is more stable than $4 s^{2} 3 d^{4}$

Solution:

$Cr has [Ar] 4 s^{1} 3 d^{5}$ electronic configuration because half filled orbital

are more stable than other orbitals.
