For n =3,l =0,1,2 i.e. l, has three values which means that it has three sub shells [3s, 3p and 3d].For a given value of l, m= -l to +l including zero.
Thus, for s-subshell l = 0, m= 0 which means s-subshell consists of only one orbital
For p-subshell l =1,m=-1,0,+1 which means p-subshell has three orbitals.
For d-subshell l = 2, m = - 2,- 1, 0, + 1 + 2 which means d-sub shell has five orbitals.
These orbitals are 3s, 3px, 3py, 3pz, 3dxy, 3dyz, 3dx2-y2 and 3dz2.
