Principal quantum number "n" relates to the energy level, which can be related to the electron "shell". n is the shell containing the outermost electron of the atom. For example, the outer electron of sodium is in the 3rd shell, so an electron in sodium can have n value from 1 to 3.
"l" is the azimuthal quantum number, and describes the type of sub sell (s, p, or d orbitals have l values of 0, 1, and 2 respectively). l can vary from 0 to (n-1) as the orbital with l = 1 (the first p oribitral) is actually part of the second electron shell (n=2), and the first orbital with l=2 (the first d oribital) is part of the third electron shell (n=3), etc.
