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 ?

A

P has greater energy than Q

B

P and Q represent the same electron

C

P and Q have same energy

D

P has less energy than Q

Text Solution

Verified by Experts

The correct Answer is:
A
From the available information , it is clear that
P electron belongs to 3d orbital
Q=electron belongs to 3s orbital
`:.` P electron has therefore , more energy.
