2. Which combination of quantum numbers cannot describe an electronic state of a hydrogen atom?
(A) n = 4, l = 3, ml = 2
(B) n = 5, l = 3, ml = 3
(C) n = 5, l = 4, ml = 2
(D) n = 4, l = 4, ml = 2
(E) n = 5, l = 3, ml = 2
All of the above combination of quantum numbers cannot describe an electronic state of a hydrogen atom.
The above options from (A) to (E) n value is 4 or 5 and l value is 3 or 4 it means electron present in 4 th or 5 th shell and it occupies d or f orbital. But in hydrogen atom electron present in 1st shell and it occupies s orbital.
