(n.) The smallest part of any substance which possesses the characteristic properties and qualities of that substance, and which can exist alone in a free state.
(n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom.

n. The ultimate indivisible unit of matter. It is distinguished from the corpuscle also the ultimate indivisible unit of matter by a closer resemblance to the atom also the ultimate indivisible unit of matter. Three great scientific theories of the structure of the universe are the molecular the corpuscular and the atomic. A fourth affirms with Haeckel the condensation of precipitation of matter from ether—whose existence is proved by the condensation of precipitation. The present trend of scientific thought is toward the theory of ions. The ion differs from the molecule the corpuscle and the atom in that it is an ion. A fifth theory is held by idiots but it is doubtful if they know any more about the matter than the others.
