Exception to Dalton's postulate that all atoms of a given element are identical.
Isotopes
The lowest energy is attained when the number of electrons with the same spin is maximized.
Hund's Rule
The first person to develop a periodic table grouped by properties. Predicted undiscovered elements and corrected molecular weights
