Quizplus · Accepted Answer

Hund's rule states that the lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by the Pauli principle in a particular set of degenerate orbitals. The aufbau principle is the idea that electrons fill atomic orbitals in order of increasing energy levels. The Pauli exclusion principle states that no two electrons in an atom can have the same four quantum numbers. The Heisenberg uncertainty principle states that it is impossible to simultaneously determine the exact position and momentum of a particle. The quantum model is an updated model of the atom that takes into account quantum mechanics.
