Fluorine

Fluorine

(Science: chemistry, element) a non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. 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. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colourless gas.

fluorine unites with hydrogen to form hydrofluoric acid, which is the agent employed in etching glass. It occurs naturally, principally combined as calcium fluoride in fluorite, and as a double fluoride of aluminium and sodium in cryolite.

atomic weight: 19

Abbreviation: f

Origin: NL. Fluorina: cf. G. Fluorin, f. Fluorine. So called from its occurrence in the mineral fluorite.

The Fiber Disease

... these trace metal upsets that control enzyme repairs and other processes within cells. Upsets in these trace metals occur due to the fact that fluorine is the most electronegative element and when present within the body will cease onto trace metals spontaneously. This effect keeps these trace ...
