• how to write the electron configuration for an atom.
• the energies and positions of electrons according to the quantum mechanical model.
• the relationship between the wavelength and frequency of light.

Distinguish:

• between quantum mechanics and classical mechanics.

Explain:

• how the frequencies of emitted light are related to changes in electron energies.
• why the actual electron configurations for some elements differ from those predicted by the aufbau principle.
