The global market for chemicals from fluorine was about US$16 billion per year as of 2006. [1] The industry was predicted to reach 2.6 million metric tons per year by 2015. [2]
Fluorine is an important element for biological systems. From a mammalian health perspective, it is notable as a component of fluorapatite , a key mineral in the teeth of humans that have been exposed to fluorine, as well as shark and fish teeth. [ 4 ]
Fluorine atoms have nine electrons, one fewer than neon, and electron configuration 1s 2 2s 2 2p 5: two electrons in a filled inner shell and seven in an outer shell requiring one more to be filled. The outer electrons are ineffective at nuclear shielding , and experience a high effective nuclear charge of 9 − 2 = 7; this affects the atom's ...
Adding a fluorine increases both its medical power and anti-inflammatory effects. [16] Fluorine-containing fludrocortisone is one of the most common of these drugs. [17] Dexamethasone and triamcinolone, which are among the most potent of the related synthetic corticosteroid class of drugs, contain fluorine as well. [17]
HFC-134a (1,1,1,2-Tetrafluoroethane) has grown to become the most abundant HFC in Earth's atmosphere as of year 2015. [2] Perfluorocarbons (PFCs) are the compounds consisting of fluorine and carbon. They are widely used in the electronics, cosmetics, and pharmaceutical industries, as well as in refrigeration when combined with other gases.
Fluorine, in the form of fluoride, is considered to be a micronutrient for human health, necessary to prevent dental cavities, and to promote healthy bone growth. [28] The tea plant (Camellia sinensis L.) is a known accumulator of fluorine compounds, released upon forming infusions such as the common beverage. The fluorine compounds decompose ...
When the local economy is strong, it contributes to the larger, broader economy in a positive way. Gabe Krajicek, CEO of Kasasa , said small business success means more local money and tax dollars ...
Several important inorganic acids contain fluorine. They are generally very strong because of the high electronegativity of fluorine. One such acid, fluoroantimonic acid (HSbF 6), is the strongest charge-neutral acid known. [30] The dispersion of the charge on the anion affects the acidity of the solvated proton (in form of H 2 F +
