The modern model of the atom is based on quantum mechanics. They produce theories or models that are eventually incorporated into the body of chemistry and used by synthetic chemists to make compounds with new, and frequently useful, properties. A physical chemist may study such things as the rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level.
