The correct set of four quantum numbers for the outermost electron of sodium (Z=11) is

A

`3,1,0,1/2`

B

`3,1,1,1/2`

C

`3,2,1,1/2`

D

`3,0,0,1/2`

Text Solution

Verified by Experts

The correct Answer is:
D
The electronic configuration of Na(Z=11) is `1s^(2)2s^(2)2p^(6)3s^(1)`. The outermost orbital is 3s.
`:.n=3, l=0, m=0, s=+1/2`
