Which one of the following sets of quantum numbers represents the highest energy level in an atom?

Options

A. n=4,l=0m=o,s=`+(1)/(2)`
B. n=3,l=1,m=1s=`+(1)/(2)`
C. n=3,l=2,m=-2,`s=+(1)/(2)`
D. n=3,l=0m=0,s=`+(1)/(2)`

Answer

C

Explanation

The orbital with highest (n+l) value will have the highest energy .In the given sets n=3 ,i=2,m=3=-2,s=+1/2 have n+l=5 i.e., 3d orbital has the highest energy.
