Know:
- light equations
- light being described as a quanta, rather than a purely as a wave (why this is important)
- absorption and emission spectra and how they relate to energy levels in an atom
- wave-particle duality of an electron (specifically that they act like standing waves....how that relates to energy levels)
- 4 quantum numbers
- principles (Aufbau, Pauli, Hund)
- electron configurations (short and long form)
