Spin up and Spin down

Postby CNourian2H » Sun Oct 20, 2019 9:09 pm

I am really confused with the spin up and spin down aspect we discussed in class. Can someone clear it up for me?
I also remember him saying that when both electrons are spin up, they interact differently than when they are spin down. Why?

I am also very confused on this topic and how to tell if they are parallel or paired?

If all orbitals of an energy level are occupied by single electrons, then these electrons are considered parallel and thus have the same spin. However, once there are two electrons per orbital, these two electrons have opposite spin. These electrons have opposite spin because no two electrons can have the same 4 quantum numbers.
