Question

Which orbital that would never exist in the quantum description of an atom is _____.

(a) 3d
(b) 1p
(c) 2s
(d) 4f

Answer 1

C. 2s

Step-by-step explanation:

the "s" orbital is only possible at an energy level of n = 1. 2s means the energy level is at n = 2 and that's not possible for the "s" sublevel.
