Etymology: "Valens" is the Latin present participle of "valere," meaning "to be strong, to be well, to have power." English borrowed it directly, and in chemistry it took on a specific technical sense: a substance's valence is its capacity to combine with other atoms, and an atom or group described as "valens" is one that is capable of bonding. The adjective therefore carries the older Latin idea of strength or power into the vocabulary of molecules. The same Latin root gave English "valence," "valiant," and "value," all tracing back to the notion of being strong or worthy. A chemist calling an atom "valens" is, in effect, describing how much force it can exert on its neighbours. The Latin sense of "being well" and "having worth" survives in the everyday words, while the chemical use narrows that vigour to a precise measure of combining power.
