Document Summary

We can figure out how many orbitals there are from the list of possible orbital (electron config list) values. To figure out how the electrons position themselves, we need to know two rules: No two electrons in the same atom can have the same set of four quantum numbers . This sets the maximum number of electrons that can occupy a given subshell. This also means that two electrons in the same orbital must have opposite spin. Electrons will always have spins parallel to the nucleus (+ ) if possible see pauli exclusion principle ^^ for whether it is possible or not! There are two main categories of exception: If one level does not completely fill, but another level -- higher on the list -- is occupied. It has been observed that there is extra stability to: Half filled subshells (slightly less stability gained vs. fully filled)
