(III)   n=3,  l=0,  m1=−1\mathrm{(III)}\,\,\,n = 3,\,\,l = 0,\,\,{m_1} = - 1
(IV)   n=3,  l=2,  m1=0\mathrm{(IV)}\,\,\,n = 3,\,\,l = 2,\,\,{m_1} = 0
(V)   n=3,  l=3,  m1=−2\mathrm{(V)}\,\,\,n = 3,\,\,l = 3,\,\,{m_1} = - 2
Of these question state designation which does not describe an allowed state for an electron in an atom?
View answer and explanation
Correct option: B
III and V
Option B (III and V) is correct because in option III, mlm_l cannot be -1 when l=0, and in option V, l cannot be 3 when n=3.
