Fluorine Essay

atomic number 9 April 6th, 2011 Fluorine is the intimately reactive chemical fixings and the lightest ingredient of the halogen elements. Fluorine is a nonmetal and is part of separate 17 (group VIIa) of the periodic table. Its density is 0.001696 grams per cubic centimeter. Its chemical performance tail assembly be attributed to its extreme ability to realise and to the small surface of its atoms. Fluorine is a corrosive disgusted yel start 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 can with a capable flame in degree Fahrenheit. 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 pe r 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 fluor (or fluorite) was described in 1529 by the German physician and mineralogist Georgius Agricola.

It appears presumable an unknown English glass cutter first hustling the megascopic hydrofluoric acetous in 1720. In 1771 the Swedish chemist Carl Wilhelm Scheele obtained hydrofluoric harsh in an impure call down by change fluorspar with concentrated sulfuric acid in a glass retort, which was greatly corroded by the product; as a result, vessel! s made of metal were employ in incidental experiments with the substance. The nearly anhydrous acid was prepared in 1809, and ii 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 undecomposed essay, order it on our website: BestEssayCheap.com
