Etymology: Fluorine was named by Humphry Davy in 1813, when he was working on hydrofluoric acid and could not isolate the element it contained. The name comes from Latin "fluor," meaning "flow," a reference to the mineral fluorspar, which was used as a flux in metalworking because it made other substances melt and run more easily. Davy added the "-ine" ending, the same suffix found in chlorine, which he had also named, and the two names were built to match. The plural "fluorines" is simply the count form of this element name, used when referring to several samples or several atoms of the element. Its ending comes from the same "-ine" suffix that makes the singular noun.

Synonyms: halogens, elements, fluorine atoms, chemical substances, fluorides
