This primer provides a systematic and rigorous introduction to the spectra and electronic structure of atoms, beginning with the hydrogen atom, and following a logical progression through the alkali metals, and the helium atom, to atoms with many unpaired electrons. Emphasis is placed on the explanation of the observed spectra using elementary quantum theory.
