Consider the ground state `Cr` atom `(Z = 24)`. The number of electron with the azimuthal number `l = 1` and `2` ,respectively are

A

16, 5

B

16, 4

C

12, 4

D

12, 5

Text Solution

Verified by Experts

The correct Answer is:
D
Cr(Z=24)`1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(1)3d^(5)`
No. of p-electrons (l=1)=12 electrons
No. of d-electrons (l=2)=5 electrons
