Recall that the quantum numbers are:


• Principal Quantum Number (n): deals with the size and energy of the atomic orbital

  • The possible values for n are 1 to ∞.


• Angular Momentum Quantum Number (l): deals with the shape of the atomic orbital

  • The possible values for l are 0 to (n – 1).


• Magnetic Quantum Number (ml): deals with the orientation of the atomic orbital in 3D space. 

  • The possible values for ml is the range of l: –l to +l.


 Spin quantum number (ms): describes the electron spin

  • There are only two possible values: +½ (spin up electron) or½ (spin down electrons)
