It is equal to the molecular weight of the ion, divided by 96.537 times its valency.
It is the river valency of which he speaks, the more important of the streams that join just above the haven.
The term “valency” is not altogether an easy one to define; we will, however, here do our best to make plain its significance.
Hydrogen, however, appears to be invariably univalent, and is therefore taken as the unit of valency.
The phenomena of valency find their explanation in modern views concerning the constitution of atoms (see § 81).
The number above each column indicates the valency which the elements of each group exhibit towards oxygen.
The question next arises, is the valency of an element fixed or variable?
If the word be defined as above, it is absolutely certain that the valency varies.
Just why different elements should differ thus in valency no one as yet knows; it is an empirical fact that they do.
Another consequence of the doctrine of valency was that it permitted the graphic representation of the molecule.
