Quantum Theory Rules and Principles

Question	Answer
Octet Rule	Atoms are most stable with eight electrons in the outer shell.
Hund's Rule	Each orbital in a sublevel must have one electron before they begin to pair up.
Pauli Exclusion Principle	1. No two electrons in the same atom can have the same set of 4 quantum numbers. (Two electrons could not occupy the same space at the same time.) 2. Two electrons in the same orbital must have opposite spins.
Aufbau Principle	Electrons fill orbitals from low energy to high.
Heisenberg Uncertainty Principle	It is fundamentally impossible to know precisely both the velocity and position of an electron at the same time.
