Fluorine is the most reactive and the most electronegative of all the elements.
Fluorine is a pale yellow, diatomic, highly corrosive, flammable gas, with a pungent odor. It is the lightest halogen.
It reacts violently with water to produce oxygen and the extremely corrosive hydrofluoric acid.
Structure:cubic crystals in solid phase
Fluorine is highly toxic and corrosive.
Compounds of fluorine, including sodium fluoride, are used in toothpaste and in drinking water to prevent dental cavities.
Hydrofluoric acid can dissolve glass and is used to etch the glass in light bulbs and in other products.
Chlorofluorocarbons (CFCs) were used in as refrigerants in air conditioning units and freezers but they have now been banned because they contribute to ozone depletion.
