Orbitals

How do you find the Ms value when finding n, l, ms, and ml?

[Ricky Ma DIS 4E]

ms is the spin of the electron. There is no way to knowing, you can characterize it with either a +1/2 spin or -1/2 spin. It will always be those two. It doesn't matter just make sure that in an orbital, there is a maximum of two electrons, each with opposide spin.

The only rule regarding Ms is that it can take on values of either +0.5 or -0.5 (spin up or spin down). It does not depend of any of the previous quantum numbers.

Ms is the spin quantum number. An electron will always be either spin up or spin down. Ms will either be +1/2 or -1/2. You can choose if you want the electron to have the quantum number +1/2 or -1/2. Due to Hund's Rule, electrons in the same subshell occupy different orbitals with parallel spin. If 2 electrons are in the same orbital then they have opposite spin.
