Term | Definition |
---|---|
n= | Principle Quantum Number |
l= | Shape of an orbital |
ml= | Orientation on x, y, or z axis |
ms= | Spin of the e- |
Aufbau Principle(Niels Bohr) | e- are added one at a time to the lowest energy sublevels until all are filled |
Pauli Exclusion Principle(Wolfgang Pauli) | Only put 2e- in each orbital and give them opposite spins |
Hund's Rule(Friedrich Hund) | Put 1e- in each orbital of a sublevel before pairing e- |
Dalton | Proposed the very 1st atomic theory |
Isotope | Same # of p+, different # of n* |
