The chemical element (symbol F) with an atomic number of 9
A fluorine atom

an octahedron of fluorines.

It is a pungent, corrosive, colorless gas
If set free it immediately attacks the containing material, so that it was not isolated until 1886
It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels
Symbol F
{i} nonmetallic chemical element
Atomic weight 19
A gaseous element that can be poisonous
The lightest halogen, it is the most reactive element, forming compounds with all others except helium, neon, and argon (the lighter noble gases). Its only valence is 1, in F2 (the diatomic molecule) and fluorides. A toxic, pale yellow gas with a pungent odour, it can be produced only by electrolysis under special conditions. Its chief source is fluorite; it also occurs in cryolite, fluorapatite, seawater, bones, and teeth. Hydrogen fluoride (HF) is a raw material for many other fluorides. Its water solution, hydrofluoric acid, is used to clean metals and to polish, etch, or frost glass. Other fluorides are useful catalysts and raw materials. Sodium fluoride (NaF) is added to water and tin fluoride (SnF2) to dental-care products to reduce dental caries (see fluoridation of water). Fluorocarbons are hydrocarbons in which some hydrogen atoms have been replaced by fluorine atoms; examples include Freons and Teflon
Used commercially in the form of sodium fluoride it is a dangerous free radical, and one of the 100 most toxic substances known to exist Sodium fluoride has been and is being added to municipal drinking water, toothpaste and is used to treat the teeth of children in an attempt to prevent dental cavities There have been cases of children being injured or even dying from fluoride poisoning as a result of accidentally swallowing their fluoride treatment while in the dentist chair
Fluorine is a pale yellow, poisonous gas. It is used in the production of uranium and other chemicals. a chemical substance that is usually in the form of a poisonous pale yellow gas. It is a chemical element : symbol F (fluor; FLUORESCENT). Nonmetallic chemical element, chemical symbol F, atomic number
The lightest of the halogens that can substitute for hydrogen in many organic compounds The resulting compounds are generally less flammable but more toxic and persistent in the environment
A non-metallic, gaseous element, strongly acid or negative, and associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member
a nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite
