How are quantum numbers used to describe electrons
... Pauli exclusion principle—no two electrons in an atom can have the same set of four quantum numbers If electrons are in the same orbital, they must have __________________spins so the fourth quantum number is different. We illustrate this by drawing one arrow up and one arrow down. Hund’s rule—for o ...
