fluorine
英 ['flʊəriːn; 'flɔː-]
美 ['flɔrin]
助记提示
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.
中文词源
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。
