azimuthal quantum number ()|
magnetic quantum number (m)
The number of possible orbitals in a subshell is determined by the number of possible m values for the subshell. Think of m as a label for individual orbitals within the subshell. For every m value that is allowed, there is one orbital in the subshell.
Allowed values of m are integers between - to +, including zero.
|possible values of m||number of orbitals in this subshell|
|1||-1, 0, +1||3|
|2||-2, -1, 0, +1, +2||5|
|3||-3, -2, -1, 0, +1, +2, +3||7|
Each orbital can hold a maximum of two electrons, so the maximum number of electrons you can put into the subshells are 2, 6, 10, and 14 for s, p, d, and f subshells, respectively.
