- uncertainty principle
- it is impossible to know both the precise location and precise velocity of a subatomic particle at the same time. (Heisenberg)
- Louis de Broglie
- suggested that particles have wavelike characteristics like light
- Max Planck
- quantum theory of light, light has wavelike and particle like characteristics
- Pauli Exclusion Principle
- in a given atom no two electrons can have the same set of 4 quantum numbers.
- Aufbau Principle
- the procedure used to find the ground state electron configuration of an atom or ion
- Hund's Rule
- electrons will occupy empty orbitals before pairing up in the same orbital
-
