1. Emission spectra and energy levels

   The electromagnetic spectrum, continuous vs line spectra, the hydrogen emission spectrum, and discrete energy levels.

2. Orbitals and electron configuration

   Sub-levels and orbital shapes, and writing electron configurations with the Aufbau principle, Hund’s rule and the Pauli exclusion principle.

3. Ionization energy

   The convergence limit as ionization, trends in first ionization energy, and using ionization data.
