记忆方法

1. “氯”是对该词的意译，“氯”是一个形声字，由形旁“气”(表示该物质是一种气体)和声旁“录”(取自“绿”字的右半部分，这个声旁既去了“绿”音，也取了“绿”的义，表示该物质是一种绿色的气体)，由此我们可以得出“氯”的字面含义为：一种绿色的气体，或者说：一种呈绿色的、常温下为气体的化学物质；并且它的发音由此也就取“绿”的音，即与“绿”的发音相同。
2. 而这个英语单词也同样表示这是一种绿色的化学物质：chlor- "green, pale green" + -ine "chemical suffix".
3. chlor- (谐音“可绿儿”).
4. 克洛里斯（Chloris）是春天、花卉和自然女神。她嫁给了西风神仄费罗斯（Zephyrus）。她在罗马神话中的名字是佛洛拉（Flora）。

英语词源

chlorine

chlorine: [19] Chlorine is a greenish-yellow gas, and was named for its colour. The term was coined by the British chemist Sir Humphry Davy in 1810, from the Greek khlōrós ‘greenishyellow’. Of other words containing this element, chlorophyll [19] too was based on the notion of colour (in reference to the green colouring matter of leaves: the Greek elements literally mean ‘green leaf’), but chloroform [19], originally French, is a secondary formation based ultimately on chlorine (since it was originally regarded as a trichloride of formyl).

=> yellow
