Chapter 5 - Electrons in Atoms - 5.2 Electron Arrangement in Atoms - 5.2 Lesson Check: 10

Answer

The Aufbau Principle states that the lowest energy levels must be filled before the higher ones. The Pauli Exclusion Principle states that each level of energy can hold 2 electrons. Hund's rule states that only one electron may be put in an orbital before pairing them up in the case that all the orbitals are full.
