Fluorine

Name: farad Symbol: F Atomic attract: 9 Atomic Mass: 18.998404 amu Melting Point: -219.62 °C (53.530006 K, -363.31598 °F) Boiling Point: -188.14 °C (85.01 K, -306.652 °F) Reactivity or inhering rubber Concerns Fluorine Elemental fluorine and the fluoride ion ar extremely toxic. The free division has a characteristic pungent odour, noticeable in concentrations as low as 20 ppb, which is beneath the safe work level. The recommended maximum whollyowable concentration for a periodical 8-hour time-weighted photograph is 1 ppm. Safe handling techniques enable the impart bland fluorine by the ton. Occurrence Fluorine Fluorine is a root 17 element. Fluorine is the n azoic negatively charged and reactive of all elements. It is a pale yellow, corrosive gas, which reacts with lots all essential and inorganic substances. Finely divided metals, glass, ceramics, carbon, and nevertheless water fuel in fluorine with a lustrous as a new penny(pr edicate) flame. It is not eccentric to know fluorine spelled incorrectly as fluorine. Fluorine is the around disconfirming and reactive of all elements. It is a pale yellow, corrosive gas, which reacts with most organic and inorganic substances. Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame.

Until valet War II, there was no commercial doing of elemental fluorine. The nuclear bomb project and nuclear nix applications, however, made it infallible to produce large quantities. History Fluorine In 1529m Georigius Agricola expound the use of fluorite as a flux, and as early as 1670 Schwandhand found that glass was etche! d when heart-to-heart to fluorspar treated with acid. Scheele and many later investigators, including Davy, Gay-Lussac, Lavoisier, and Thenard, experimented with hydrofluoric acid, some experiments termination tragically. The element was finally isolated in 1866 by Moissan later roughly 74 years of continuous effort. Uses Fluorine Fluorine and its compounds are used in producing uranium (from...If you want to get a full essay, order it on our website: BestEssayCheap.com
