The electronic configuration of chromium (Z = 24) is

A

41678

B

2, 8, 8, 6

C

2, 8, 12, 2

D

2, 8, 13, 1

Answer

2, 8, 13, 1

Explanation

Solution

Electronic configuration of Cr24 =1s2⏟2 2s2 2p6⏟8, 3s2, 3p6 3d5⏟13, 4s1⏟1Cr_{24} \, = \underbrace{1s^2}_{2} \, \underbrace{ 2s^2 \, 2p^6}_{ 8 } , \, \underbrace{ 3s^2, \, 3p^6 \, 3d^5 }_{ 13}, \, \underbrace{ 4s^1 }{ 1} Thus, the electronic configuration of Cr is 2, 8, 13, 1.
