Quantivalence ofRadicals—“When in the molecule of any compound the
dominant or central atom is united to as many other atoms as it can hold of that
kind, the molecule is said to be saturated. Thus HCl, H20, H3N, and H4C are all
saturated ...

An atom which has the same chemism as an atom of hydrogen, has a
quantivalence of one, as chlorine ; one which can displace two atoms of
hydrogen, has a quantivalence of two, as oxygen, sulphur, and so on to three,
four, five, six and ...

... by chemists on the theories of equivalence and qnantivalence, than a
comparison of the opinions which those remarks have called forth. Mr. Ward
regards atomicity and quantivalence, equivalent and atomic weight, as
synonymous terms.

On the Constancy of Quanlivalenee, by John A. R. Newlands, F.C.S. The object
of this communication is to indicate a process by which the quantivalence* of the
elementary bodies may be viewed as invariably exerted to its fullest extent.

Introduction to Chemical Science
It will be seen that some elements have a variable quantivalence. Sn has either 2
or 4; P has 3 or 5. It usually varies by two for a given element, as though a pair of
bonds sometimes saturated each other;. e.g. =Sn=, a quantivalence of 4, and ...

quantivalence increases by two bonds, and never by a. single bond. The
explanation is thought to be that the bonds of any atom when not in use to hold
other atoms, are ...
