  6. The physical properties of the chemical element Fluorine are: • Standard State (phase): Gas • Specific Heat Capacity: 31.304J/mol·1/K • Heat of Fusion: 0.51kJ/mol • Heat of Vaporization: 6.62kJ/mol • Melting Point (K): 53K • Melting Point (°C): -219°C • Melting Point (°F): -363°F • Boiling Point (K): 85K • Boiling Point (°C): -188°C • Boiling Point (°F): -306°F Physical Properties

  7. Chemical Properties It react with all elements other than nitrogen, oxygen, and lighter noble gases at room temperature. it belongs to group VII-A (7-A) of the periodic table and its the lightest member of that group. Its melting point is -219.61 Degree centigrade and its boiling point is -188.13 Degree centigrade Read more: http://www.lenntech.com/periodic/elements/f.htm#ixzz2OqxdJxgQ

  8. Uses • Some compounds of fluorine (such as sodiumfluoride, 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

  9. Joseph Henri MoissanDiscovered Fluorine in 1886

  10. Important Compounds The 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 recentlythere is a move to find alternative refrigerants because these can damage the ozone layer.

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