Question

Which of the following quantum number for orbitals in hydrogen atom has a greater energy of electrons ?
(i) `n=3,l=2` and `m_(l) +1`
(ii) ` n= 3 , l=2` and `m_(l) = -1`

Answer 1

They have same energy , as `( n +1)` value is same but `m_(l)` values are different which govern the orientation of orbitals, so energy is same but different orientations.
