Uses
• Some compounds of fluorine (such as sodium fluoride, stannous fluoride and
sodium MFP) are added to toothpastes to prevent dental cavities. These are now regularly added to water as well.
• Most general anesthetics are derived from compounds of fluorine.
• Fluorine-18 emits positrons and has a relatively large half-life. This makes it ideal for use in positron emission topography.
• Anti-reflective coatings contain compounds of fluorine.
• Fluorine can be used for plasma etching, flat panel display and MEMS (microelectromechanical) fabrication.
• HF (hydrofluoric acid) is used to etch glass, usually in light bulbs

Important CompoundsThe ones you probably use the most:
Sodium Fluoride (NaF) it's put into drinking water and toothpaste to hep prevent tooth decay.
Polytetrafluoroethylene (-[C2F4]n-) - You probably know it by the trade name Teflon, it's used to prevent food from sticking to pans, amongst other things.
Chlorofluorocarbons (CClxFx) - There's a variety of these, many of them are sold under the name Freon. Historically they have been used in refrigerators and air conditioners,
though recently there is a move to find alternative refrigerants because these can damage the ozone layer.

Interesting Facts
• Fluorine acts violently with almost all elements, organic compounds, inorganic compounds including water.
