This chapter applies quantum mechanics and its approximations to some elementary atomic physics questions. It also applies the so-called Hartree–Fock approximation and discuss how one can go beyond it. It also discusses spin–orbit coupling and how to fully characterize the atomic states.

*Keywords:*
Hartree–Fock approximation, atomic states, atomic configuration, configuration interaction approximation, Jastrow wavefunction, Hund’s rule, spin–orbit interaction in atoms
