Question

17. Which of the following quantum number gives the shape of atomic orbital of sub-shell?
(A) n
(B) 1
(C) m
(D) s​

Answer 1

Answer:

The shape of a subshell is described by the quantum number ℓ. ℓ can be any positive integer from 0 to n-1. So, there is the possibility of many subshells of many shapes. Since subshells of a shell share the space of that shell, they must have the same energy levels.
