How does a fluorine atom form a fluoride ion
Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. See more Fluoride is an inorganic, monatomic anion of fluorine, with the chemical formula F (also written [F] ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and … See more Fluorine is estimated to be the 13th-most abundant element in Earth's crust and is widely dispersed in nature, entirely in the form of fluorides. The vast majority is held in mineral deposits, the most commercially important of which is fluorite (CaF2). Natural weathering … See more Fluoride salts and hydrofluoric acid are the main fluorides of industrial value. Organofluorine chemistry Organofluorine compounds are pervasive.
