fluorine (symbol F) Gaseous toxic element of the halogen group (elements in group VII of the periodic table), isolated in 1886 by Henri Moissan. Chief sources are fluorspar and cryolite. The pale yellow element, obtained by electrolysis, is the most electronegative element and the most reactive nonmetallic element. It is in fluoride in drinking water and is used in making fluorocarbons and in extracting uranium. Properties: at.no. 9; r.a.m. 19; m.p. −219.6°C (−363.3°F); b.p. −188.1°C (−306.6°F); single isotope F¹⁹.
