The number of electrons with azimuthal quantum number `l=1andl=2` for `Cr` in ground state respectively are

A

12, 5

B

16, 4

C

12, 4

D

16, 3

Text Solution

Verified by Experts

The correct Answer is:
A
Electronic configuration of
`"_(24)Cr=1s^(2),2s^(2),2p^(6),3s^(2),3p^(6),4s^(1),3d^(5)` Given, azimuthal quantum number `(l)=1rArr"p-orbital"`
azimuthal quantum number `(l)=2rArr"d-orbital"` So, number of electrons in p-orbital = 12 and numaber of electrons in d-orbital = 5.
