Question

Magnetic quantum number specifies _______

Answer 1

1. The magnetic quantum number refers to the different orientations of the electrons present in a sublevel.
2. Since each orientation corresponds to an orbital, we can say that the magnetic quantum number determines the number of orbitals present in any sublevel.
3. There are $(2\mathrm{l}+1)$ permitted integer values of magnetic quantum numbers for a given value of the azimuthal quantum number.
4. Therefore magnetic quantum number specifies the orientation of orbitals in space.
