Description of a molecule
Webmolecule: [noun] the smallest particle of a substance that retains all the properties (see property 1a) of the substance and is composed of one or more atoms (see atom 1a). The definition of the molecule has evolved as knowledge of the structure of molecules has increased. Earlier definitions were less precise, defining molecules as the smallest particles of pure chemical substances that still retain their composition and chemical properties. This definition often breaks down since many substances in ordinary experience, such as rocks, salts, and metals, …
