Question

for which of the following sets of quantum numbers an electron will have the highest energy?
1: 3,2,1,1/2
2:4,2,-1,1/2
3:4,1,0,-1/2
4: 5,0,0,1/2

Answer 1

Answer:

Correct option is

2) :- 4,2, −1 , 1/2

Energy depends on (n+l)

A→(n+l)=5

B→(n+l)=6

C→(n+l)=5

D→(n+l)=5

∴ Max energy for B
