QUANTUM NUMBERS
Quantum Numbers
Y the atomic wavefunction, also called an
atomic orbital (orbital), is specified by three quantum numbers.
e.g. 2px (n=2, l=1, ml=‘-1’)
Y the atomic wavefunction, also called an

Principal quantum number- n
(size) n = 1 ...N Defines the shell
(size) n = 1 ...N Defines the shell
Angular quantum number- l (azimuthal) (shape) l = 0 ...n-1 Defines the subshell
l = 0 = s, l = 1 = p, l = 2 = d
Magnetic quantum number- ml
(orientation) ml = -l ...0...+l
(orientation) ml = -l ...0...+l
