| 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. |
