Quantitatively, we can find ml by taking negative l to positive l. ml basically tells us how many orbitals there are present and their orientation within a subshell. Ie, we are given a 3p subshell- n would be 3, l would be 2 (n-1), and the possible solutions for ml would be -2,-1,0,1,2.

The magnetic quantum number ml determines the number of orbitals and their orientation within a subshell. Its value depends on the orbital angular momentum quantum number l. Given a certain value for l, ml is an interval ranging from the negative value of l to the positive value of l, so it can be zero, a negative integer, or a positive integer. For example if n=3, then l (which is n-1) = 2, and therefore the possible values of ml are -2, -1, 0, 1, or 2.
