A salt of fluorine (F2) with a negative electric charge. A mineral found in soil, food, water, a substance that has been used as an ingredient for the prevention of tooth decay. And strengthen bones and teeth like toothpaste, supplements, but if it gets too much is toxic to the body, such as dental fluorosis on bone. And a fiber Or
fluorine (F2) was among the seven lightest element and is sensitive to the reaction as soon as possible. Therefore, no fluorine-free form in nature. But are found in fluoride has a negative charge. And fluoride ions (F-) ions, which are similar to hydroxide ions (OH-) are always well represented in the mineral fluoride. Is a very common element is ranked 17th in the earth's crust is inert (halogen) are pale yellow. A reactive gas And can be oxidized to have a positive charge. No fluorine in an independent state. It is found in the nature of the compounds with other elements fluoride in minerals, usually in the form of mineral fluoride Wright (CaF2) or sapphire soft mineral that is found fluoride were the source. Luo Spartak (Fluorspar), Christie's Delight (Cryolite), Forest Tithe (Apartite), Kingston Honda Blake Sand, rock phosphate and fluoride, which makes out to be. in fluoro-silicate.
