The quantum number n=4 refers to the fourth energy level of an atom. The magnetic quantum number ml=0 refers to the orientation of the orbital in space.

For n=4, the possible values for the angular quantum number l can be 0, 1, 2, or 3.

When l=0, we have an s orbital, and for any s orbital, ml can only be 0. So, there is 1 orbital here.

When l=1, we have p orbitals, but for p orbitals, ml can be -1, 0, or 1. So, there is 1 orbital here with ml=0.

When l=2, we have d orbitals, and for d orbitals, ml can be -2, -1, 0, 1, or 2. So, there is 1 orbital here with ml=0.

When l=3, we have f orbitals, and for f orbitals, ml can be -3, -2, -1, 0, 1, 2, or 3. So, there is 1 orbital here with ml=0.

So, in total, there are 4 orbitals which can be identified with n=4 and ml=0.
