Two electrons have the following quantum numbers :
P=3, 2, -2, +1/2 , Q=3, 0, 0, +1/2
Which of the following statements is true ?

Options

A. P has lesser energy than Q
B. P and Q have same energy
C. P and Q represent same electron
D. P has greater energy than Q

Answer

D

Explanation

For P electron `n=3,l=2,m=-2,s=+1/2`
Q electron `n=3,l=0,m=0,s=+1/2`
According to (n + l) rule has greater energy than Q.
