Chemistry is the science of matter at the atomic to molecular scale, production mainly with collections of atoms, such as gases, molecules, crystals, and metals. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in daily life. Chemistry also deals with sympathetic the properties and interactions of individual atoms with the purpose of applying that knowledge at the macroscopic level. According to contemporary chemistry, the physical properties of materials are usually determined by their structure at the atomic scale, which is itself defined by interatomic forces.
