Which quantum divides shells into orbitals?
Spin
Principal
Azimuthal
Magnetic
Explication
The azimuthal quantum number determines an atom's orbital angular momentum and the shape of the orbital. The principal quantum number determines its number of shells. Magnetic quantum number determines how many orbitals there are as well as their orientation within a subshell.
