英语词汇“valence”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

1n 2n

The valence of an atom is the ability of that atom, expressed in numbers, to combine or interact with another atom, depending on the number of electrons available for bonding in the atom’s outer shell, called the valence shell.

The Latin valentia, "strength," is the basis for the word valence. It's a fitting word, as the valence of an element determines its strength — an idea that was first recorded in the later 19th Century. Since the word valence carries the idea of interaction, it can also be used to describe the amount of attraction or repulsion by people, either toward each other or an event.
