Question

The shape of an atomic orbital is associated with

Answer 1

The properties of the atomic orbital are actually dependent on the quantum numbers.

size of atomic orbital: governed by the principal quantum number (n)

shape of atomic orbital: governed by the angular momentum quantum number (l)

orientation in space: governed by the magnetic quantum number (ml)

 

Since we are asked about the shape, hence the correct answer is:

angular momentum quantum number (l)
