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 5`

B

`12 and 5`

C

`16 and 5`

D

`12 and 4`

Text Solution

Verified by Experts

The correct Answer is:
B
`Cr1s^(2)2s^(2)2p^(6)3s6(2)3p^(6)4s^(2)3d^(5) (Z = 2 4 for Cr)`
`l = 1 rArr`p orbital rArr 12 electron
`l = 2 rArr` d orbital rArr 5 electron
