fluorine 氟

来自19世纪英国化学家Humphry Davy, 因首先在氟石（fluor）中发现这种化学元素而得名。-ine, 化学名词后缀，衍生物。

fluorine (n.): non-metallic element, 1813, coined by English chemist Sir Humphry Davy (1778-1829) from fluorspar ("calcium fluoride," modern fluorite), the late 18c. name of the mineral where it was first found (see fluor) + chemical suffix -ine (2). Not isolated until 1886. Related: Fluorinate; fluorination.

记忆方法

1. flu- + -or => fluor (originally meaning "a flowing, flow").
2. => fluor: an old chemistry term for "minerals which were readily fusible and useful as fluxes in smelting". => fluorite / fluorspar.
3. fluorspar ("calcium fluoride," modern fluorite), name of the mineral where it was first found.
4. fluor + -ine (chemical suffix). So named because it is isolated from fluor / fluorite.
