Историја
In 1529, Georigius Agricola described the use of fluorspar as a flux.
In 1670 Heinrich Schwandhard found that glass was etched when exposed to fluorspar treated with acid.
In 1810, French scientist Andre-Marie Ampere proposed that fluoric acid was a compound of hydrogen with a new element.
The element was finally isolated in 1886 by Henri Moissan.

Примена
Compounds of fluorine, including sodium fluoride, are used in toothpaste and in drinking water to prevent dental cavities.
Hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) now serve as replacements for CFC refrigerants.
Fluorine and its compounds are used in processing nuclear fuel.
