Classify each statement below as True or False. Electrons "fill" orbitals of higher energy before "filling" orbitals of lower energy. The 4s subshell is higher in energy than the 3d subshell. Within a set of orbitals of equal energy, the lowest energy configuration is that having the maximum number of unpaired electrons. If an orbital contains two electrons, they must have different spins. At most two electrons in the same atom can have the same set of all four quantum numbers.
