Fluorine is thechemical elementwithatomic number9, represented by the symbol F. It is the lightest element of thehalogencolumn of the periodic table and has a single stableisotope, fluorine**9. Atstandard pressure and temperature, fluorine is a pale yellow gas composed ofdiatomic molecules, F2. In stars, fluorine is rare compared to other light elements. In Earth's crust, fluorine is more common,being the *3th most abundant element.
Fluorine's most important mineral,fluorite, was first formally described in ***0, in the context ofsmelting. The mineral's name derives from the Latin verb fluo, which means "flow," because fluorite was added to metal ores to lower their melting points. Suggested to be a chemical element in ***1, "fluorine" was named after the source mineral. Several chemists, the "fluorine martyrs," died in accidents while trying to isolate the element. In ***6, French chemistHenri Moissansucceeded. His method ofelectrolysisremains the industrial production method. The main use of elemental fluorine,uranium enrichment, was developed during the
Manhattan Project. Fluorine is the mostelectronegativeelement and forms stable compounds,fluorides, with all elements exceptheliumandneon. Because of the difficulty in making elemental fluorine, the vast majority of commercial fluorine is neverreducedto the element.Hydrofluoric acidis the keyintermediatefor the $*3 billion fluorochemical industry. Although only aweak acid, HF eats through glass and is a worse burn danger than conventionalstrong acids. The fluorides of lighter metal elements areionic compounds(salts); those of heavier metal elements are volatilemolecular compounds. The largest uses of inorganic fluorides aresteel makingand| País: | Cameroon |
