Q. In a multi-electron atom, which of the following orbitals described by the three quantum numbers will have the same energy in the absence of magnetic field:
(i) $n = 1, l = 0, m = 0$
(ii) $n = 2, l = 0, m = 0$
(iii) $n = 2,l = 1,m = 1 $
(iv) $n = 3, l = 2, m = 1$
(v) $n = 3,l = 2, m = 0$

Structure of Atom

Solution:

Orbitals having $(n + l)$ same possess same energy in absence of magnetic field.
