Question

ion n.离子 (1) 这两种粒子都能产生离子对。(2) 结晶体由氩离子轰击而净化。 Ion is a word you are most likely to encounter in a physics or chemistry text. But you don’t have to be a chemist or physicist to understand the concept. If you had a neutral particle and you were able to remove or add an electron, then you would have you have an ion — a charged particle. Don't confuse the tiny ion with the similar word eon, which is an extremely long period of time.
