Question

Which of the following orbitals described by 3 quantum numbers will have different energy in absence of magnetic & electric fields? A) n=3, l=1, m=0 B) n=3, l=2, m=0 C) n=3, l=2, m=2 D) n=3, l=2, m=1

Answer 1

Option A

Explanation:

In absence of electric or magnetic field the difference energy of two sub level under same principal level is designated by their azimuthal q.no i.e. l value.

In our case n is same for all option. l differs from other in option where it is 1 and in all other options it is 2.

m value differs when field is applied.
