- It is represented by the letter 7′ and can take integral values from zero to n – 1, where n is the principal quantum number.
- Each l value represents a subshell (orbital). l = 0, 1, 2, 3 and 4 represents the s, p, d, f and g orbitals respectively.
- The maximum number of electrons that can be accommodated in a given subshell (orbital) is 2(2l + 1).
It is used to calculate the orbital angular momentum using the expression Angular momentum = (\(\sqrt{ l(l+1)}\frac{h}{2π}\)
