1865 A. W. Hofmann Introd. Mod. Chem. 169 We are in want of a good appellation to denote this atom-fixing power of the elements. The vague and rather barbarous expression, atomicity, has drifted into use for this purpose; and the elements have been called monatomic, diatomic, triatomic... These expressions are faulty, because they are open to misinterpretation, as if intended to denote the atomic structure of the respective elementary molecules themselves... We shall escape this by substituting the expression quantivalence for atomicity and designating the elements univalent, bivalent [etc.].
