來(lái)自希臘語(yǔ)ion,走，來(lái)自PIE*ei,走，上路，詞源同ire(拉丁語(yǔ)，現(xiàn)在主動(dòng)不定式格),iter(拉丁語(yǔ)，過(guò)去分詞格),exit,itinerary.后1834年，英國(guó)物理學(xué)家Michael Faraday借用該詞來(lái)表示電磁的電離子。

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.
