In chemistry, molecule (CR:1150) (LH:12) (TL:1162|#17) is bonded structure comprised of two or more atoms; the simplest example is the ‘H molecule’ (Heitler, 1956), or dihydrogen H2, comprised of two hydrogen atoms attached via covalent bond.
In 1649, Pierre Gassendi, influenced by Beeckman, in his Arrangement of the Philosophy of Epicurus, coined the term "molecule" (molécule), as the attachment of two or more atoms, or small mass comprised of atoms.
