Linguistic Origin & Historical Etymology

The term combines 'molecular', derived from the New Latin 'molecularis' (pertaining to a molecule, from Latin 'molecula' meaning small mass), and 'formula', from Latin 'formula' meaning a fine shape, form, or rule (diminutive of 'forma'). Established in the 19th century alongside the development of modern chemical stoichiometry and atomic theory to express the exact number of atoms of each element in a chemical compound.
