ion

• n. [化学] 离子
• n. (Ion)人名；(罗、摩尔)扬；(丹)约恩

来自希腊语ion,走，来自PIE*ei,走，上路，词源同ire(拉丁语，现在主动不定式格),iter(拉丁语，过去分词格),exit,itinerary.后1834年，英国物理学家Michael Faraday借用该词来表示电磁的电离子。

1. a particle that is electrically charged (positive or negative); an atom or molecule or group that has lost or gained one or more electrons

ion (n.)

1834, introduced by English physicist and chemist Michael Faraday (suggested by the Rev. William Whewell, English polymath), coined from Greek ion, neuter present participle of ienai "go," from PIE root *ei- (1) "to go, to walk" (cognates: Greek eimi "I go;" Latin ire "to go," iter "a way;" Old Irish ethaim "I go;" Irish bothar "a road" (from *bou-itro- "cows' way"), Gaulish eimu "we go," Gothic iddja "went," Sanskrit e'ti "goes," imas "we go," ayanam "a going, way;" Avestan ae'iti "goes;" Old Persian aitiy "goes;" Lithuanian eiti "to go;" Old Church Slavonic iti "go;" Bulgarian ida "I go;" Russian idti "to go"). So called because ions move toward the electrode of opposite charge.
