The correct set of four quantum numbers for outermost electron of potassium (Z=19 ) is

A

`3,1,0,1/2`

B

`4,0,0,1/2`

C

`3,0,0,1/2`

D

`4,1,0,1/2`

Text Solution

Verified by Experts

The correct Answer is:
B
`K(Z=19),1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(1)`
For outermost electron,
`n=4,l=0,m=0,s=+1/2`
