Etymology 1

edit
 
A valence diagram of methane showing that one carbon atom can combine with a maximum of four hydrogen atoms, or that it makes four electrons available to form covalent chemical bonds, which means that it has a valence (sense 1.1) of four or is tetravalent.

Sense 1.1 (“combining capacity of an atom”) and sense 3 (“one-dimensional value assigned by a person to an object, situation, or state”) are borrowed from German Valenz + English -ence (suffix meaning ‘having the condition or state of’). Valenz is a clipping of Quantivalenz (“(archaic) valence in chemistry”), from English quantivalence, from Latin quantus (“how much”) + English -i- (interfix inserted between morphemes of Latin origin for ease of pronunciation) + Latin valentia (“bodily strength; health; vigour”) (whence Late Middle English valence (“medicinal preparation made from plants”);[1] ultimately from Proto-Indo-European *h₂welh₁- (“to rule; powerful, strong”)).[2] Quantivalence was coined by F. O. Ward who communicated it to the German chemist August Wilhelm von Hofmann (1818–1892), leading him to coin the German word Quantivalenz.[3] Doublet of value.

Sense 2 (“number of arguments a verb can have”) was formed by analogy to the use of the word in chemistry: see above.
