The set of quantum numbers for the outermost electron for copper in its fround state is

Options

A. A) `4,1,1,+1//2`
B. B) `3,2,2,+1//2`
C. C) `4,0,0,+1//2`
D. D) `4,2,2,+1//2`

Answer

C

Explanation

Electronic configuration of `Cu`
`""_(29)Cuto1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(1)`
Outermost electron is 4s sub-shell
For `4s" "n=4,l=0,m=0,s=+1//2` or `-1//2`.
