Ml Meaning

Postby rikolivares » Sat Oct 27, 2018 1:54 pm

I understand that n corresponds to the shell and l is the type of orbital but what does ml correspond to? Is this something we will need to know? Thank you!

m labels the different orbitals of a subshell (l) and also determines the orientation. I think it would be a good idea to familiarize yourself wth this concept and to also know that m = l, l-1, ..., -l

m(l) refers to the different orbitals in a subshell l.

The s-subshell (l = 0) has one orbital, so m(l) has the value of 0.

The p-subshell (l = 1) has three orbitals, so m(l) has the values of -1, 0, +1.

The d-subshell (l = 2) has five orbitals, so m(l) has the values of -2, -1, 0, +1, +2.

This pattern continues because of the correlation between l and m(l).

This is an important concept you should know to have a good understanding of quantum numbers.

ml is the magnetic quantum number, it specifies the individual orbitals within a subshell and indicates orientations. There are always 2l+1 different values of ml for a given value of l.
