- 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
