nitrogen (n.): 1794, from French nitrogène, coined 1790 by French chemist Jean Antoine Chaptal (1756-1832), from comb. form of Greek nitron "sodium carbonate" (see nitro-) + French gène "producing," from Greek -gen "giving birth to" (see -gen).

记忆方法

1. 1787年由拉瓦锡和其他法国科学家提出，氮的英文名称nitrogen，是"硝石组成者“的意思。中国清末化学家启蒙者徐寿在第一次把氮译成中文时曾写成“淡气”，意思是说，它“冲淡”了空气中的氧气。元素名来源于希腊文，原意是“硝石”。
