词根

"Electron" 这个单词是由"electr-"(电)和"-on"(用于表明这是一种粒子)两部分构成。其中"electr-"来源于希腊词"ēlektron",意为"琥珀",因古人发现琥珀摩擦时会产生静电,故用此命名。

n. 电子 [ 复数 electrons ]

强化记忆

我们可以将 "Electron" 这个单词中的 "electr-" 和 "-on" 分别和 "electric"(电)以及 "neutron"(中子)等词关联记忆,这样可以更容易记住它。"Electron" 这个词来源于希腊词 "ēlektron",它最初的意思是 "琥珀"。琥珀在古希腊时期当时就被认为有神奇的性质,因其可以通过摩擦产生静电。后来,科学家在 19 世纪末发现了这个粒子并命名为 "electron",因其带有电性。
