The question next arises, is the valency of an element fixed or variable?
It is equal to the molecular weight of the ion, divided by 96.537 times its valency.
As ions possess different electric charges, the charge on the disperse phase is subject to the valency rule.
The term “valency” is not altogether an easy one to define; we will, however, here do our best to make plain its significance.
The number above each column indicates the valency which the elements of each group exhibit towards oxygen.
The phenomena of valency find their explanation in modern views concerning the constitution of atoms (see § 81).
There is a close relationship between prevailing, valiancy, valency, and value.
Just why different elements should differ thus in valency no one as yet knows; it is an empirical fact that they do.
The benzene nucleus presents a remarkable case, which must be considered in the formulation of any complete theory of valency.
Another consequence of the doctrine of valency was that it permitted the graphic representation of the molecule.
