Solutions to the wave equation
Solutions are characterized by quantum numbers
`
The principle quantum number,
n
, is a positive
integer that indicates the shell and relative size of
orbital(s)
orbital(s).
`
The angular momentum quantum number,
l
, is an
integer from zero to n-1. It defines the shape of the
orbital and subshell.

`
The magnetic quantum number,
m
l
, is an integer with a
value from -l to +l.
It defines the orientation of an
orbital in the space around the nucleus of an atom
orbital in the space around the nucleus of an atom.
`
The spin magnetic quantum number,
m
s
, is to account
for the two possible spin orientations.
The values for
m are +1/2 and
