How are quantum numbers used to describe electrons
... 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 orbitals with the same energy (degenerate orbitals), the lowest energy is attained when the number of ...

... For the H atom the orbital energy depends only on n, so all orbitals with the same value of n have the same energy. This is not true, however, for any other atom! The H atom orbitals may be used to approximate the orbitals for multi-electron atoms. But since these atoms have more than one electron, ...
