*n*, the orbital quantum number,*l*, has all of the integer values from 0 to*n*-1. Each value of*l*represents a*subshell*.For each value of

*l*, the magnetic quantum number,*m*_{l}has all of the integer values from -*l*to +*l*. Each value of*m*_{l}represents an*orbital*.The orbital is labelled with the value of

*n*and a code for the value of*l*from the table below. If there is more than one value of*m*_{l}then a subscript is added which describes the orientation of the orbital.Orbital quantum number, l: | 0 | 1 | 2 | 3 | 4 | ... |
