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

A

12 and 4

B

16 and 5

C

16 and 4

D

12 and 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)`
l = 1 corresponds to p-subshell.
No. of electrons to p-subshell.
l = 2 corresponds in -d-subshell `= 6+6 = 12`.
No. of electrons in d-subshell =5.
