Idea

Since the nature of atoms is described by quantum mechanics and since chemistry deals with bound states of atoms – molecules – it is ultimately based on quantum physics, but typically the detailed quantum mechanical processes are heavily coarse-grained to effective laws of chemistry. In contrast to this quantum chemistry studies chemical effects explicitly with more of the detailed quantum mechanics underlying them taken into account. For example, quantum mechanics may be used to explain the periodic table of chemical elements through the occupation of their electron shells (Feynman63).
