One among the following set of quantum numbers defines the highest energy electron in scandium (I)ion

A

n=3,l=1,m=0,s=+1/2

B

n=3,l=0,m=0,s=-1/2

C

n=4,l=0,m=0,s=+1/2

D

n=3,l=2,m=2,s=+1/2

Text Solution

Verified by Experts

The correct Answer is:
C
The configuration of Sc(I) ion is `=1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(1)4s(1)`
Highest energy electron `=4s^(-1)`
`n=4, 1=0, m=0, s=+1//2`
