All of these are ways of describing the probability locations of electrons.
The first Quantum number describes the shell of the electrons The quantum number describes which shell the electrons are in.
The second Quantum number describes the type of orbital or subshell the electrons are in. s, p, d, f.
The orbitals are a probability location where the electron might be found. The orbitals are in different energy levels described by the first quantum number. The shape of the orbitals is described by the sub shell, and the second quantum quantum number.
