Introduction
Fluorine

  • first identified by Scheele in 1771AD
  • first isolated by Moissan in 1886AD
  • univalent poisonous gaseous halogen, pale yellow-green
  • most chemically reactive and electronegative of all the elements
  • reacts with nearlyall organic and inorganic materials, even withgold and platinum.
  • Hydrogen and fluorine react with explosive violence.
  •  With water, form hydrofluoric acid and ozone. A jet of fluorine from apressure container reacts
  • with human flesh and can cause extremely severe burns thatare very difficult to heal
  • forms compound with most other elements (even with noble gases krypton, xenon and radon)
  • so reactive that glass, metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas. Too reactive to stay free.
  • in water occurs as fluoride ion F-
  • attracted by positively charged ions Ca, Mg, Al,…
  • F-18, a PET isotope used for diagnostic andtherapeutic purposes
