Fluorine Essay

degree Fahrenheit April 6th, 2011 Fluorine is the intimately reactive chemical segment and the lightest ingredient of the halogen elements. Fluorine is a nonmetal and is part of classify 17 (group VIIa) of the periodic table. Its density is 0.001696 grams per cubic centimeter. Its chemical exertion tail assembly be attributed to its extreme ability to curl up and to the small surface of its atoms. Fluorine is a corrosive demented yel slump gas. It is super reactive, participating in reactions with virtually all-organic and inorganic substances. Fluorine is the most electronegative element. Metals, glass, ceramics, carbon, and water will hit the ceiling with a capable flame in atomic number 9. It is possible that fluorine can stand-in for hydrogen in organic reactions. Fluorine has been known to piddle compounds with rare gases, including xenon, radon, and krypton. Free fluorine has a characteristic acerb odor, detectable at concentrations as low as 20 parts per billion. Both elemental fluorine and the fluoride ion are super toxic. The recommended maximum allowable concentration for a daily 8-hour time-weighted word picture is 0.1 parts per million. The fluorine-containing mineral fluorspar (or fluorite) was described in 1529 by the German physician and mineralogist Georgius Agricola.

It appears credibly an unknown English glass cutter first hustling the underbred hydrofluoric acetous in 1720. In 1771 the Swedish chemist Carl Wilhelm Scheele obtained hydrofluoric deadly in an impure call down by hotness fluorspar with concentrated sulfuric acid i n a glass retort, which was greatly corroded! by the product; as a result, vessels made of metal were employ in concomitant experiments with the substance. The nearly anhydrous acid was prepared in 1809, and 2 years later the French physicist André-Marie angstrom unitère suggested that it was a compound of hydrogen with an unknown element, akin to chlorine, for which he suggested the name fluorine. Fluorspar was then recognized to be calcium fluoride. The isolation of fluorine was for a...If you want to get a enough essay, order it on our website: BestEssayCheap.com
