    • Discoverer: Henri Moissan
    • Discovery Location: Paris France
    • Discovery Year: 1886
    • Name Origin:
      Latin: fluo (flow).
    • Abundance of Fluorine:
      • Earth's Crust/p.p.m.: 950
      • Seawater/p.p.m.:
        • Atlantic Suface: 0.0001
        • Atlantic Deep: 0.000096
        • Pacific Surface: 0.0001
        • Pacific Deep: 0.00004
      • Atmosphere/p.p.m.: N/A
      • Sun (Relative to H=1E12): 0.000363
    • Sources of Fluorine:
      Found in the minerals fluorite (CaF2) and cryolite (Na2AlF6). Around 2,400 tons of fluorine gas and 4,700,000 tons of fluorite are produced each year. Primary mining areas are Canada, USA, UK, Russia, Mexico and Italy.
    • Uses of Fluorine:
      Combines more readily than any other element. Used in refrigerants and other chloro fluorocarbons. Also in toothpaste as sodium fluoride (NaF) and stannous fluoride (SnF2); also in Teflon.
    • Additional Notes:
      Fluorine gas is highly toxic and corrosive. Even exposure to low concentrations causes lung and eye irritation. Metal fluorides are also very toxic while organic fluorides are often quite harmless.
