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

A

16 and 4

B

12 and 5

C

12 and 4

D

16 and 5

Text Solution

Verified by Experts

The correct Answer is:
B
Electronic configuration of `Cr(Z = 24)` :
`1s^2 2s^2 2p^6 3s^2 3p^6 4d^5 4s^1`
No. of electrons with `l = 1` are `6(2p^6) + 6(3p^6) = 12`
No. of electrons with `l = 2` are `5 (3d^5)`.
