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.

The Physical Properties of Fluorine are as follows:
Color : It is a pale yellow, white or colourless gasFluorescence : It can sometimes be fluorescent
Solubility : In liquid form it is freely soluble in liquid oxygen and ozoneOdor : PungentDensity : A density of 1.695 grams per liter, it is 1.3 times as dense as airPhase Change - Gas to liquid : Fluorine changes from a gas to a liquid at a temperature of -188.13°C (-306.5°F)
Phase Change - Liquid to solid : Fluorine changes from a liquid to a solid at -219.61°C (-363.30°F).
The Chemical Properties of Fluorine are as follows.
Fluorine is the most chemically active non-metallic element and is the most electro-negative of all the elements.
Chemical Formula : FToxicity : Highly Poisonous at room temperatureOxidation : Does not combine with oxygenCompounds : The importance of fluorine lies largely in its compounds. Fluorite is used as a flux in refining iron. Cryolite is used in the production of aluminumCorrosion : Highly corrosive gasReactivity with water : When mixed with water, it reacts explosivelyReactivity with Elements : Reacts with all the elements except helium, neon, and argonReactivity with heat : Heat resistantFlammability : Flammable, having the ability to catch on fire
Uses
There was no commercial production of fluorine until the Second World War, when the development of the atom bomb, and other nuclear energy projects, made it necessary to produce large quantities. Before this, fluorine salts, known as fluorides, were for a long time used in welding and for frosting glass.
The element is used to make uranium hexafluoride, needed by the nuclear power industry to separate uranium isotopes. It is also used to make sulfur hexafluoride, the insulating gas for high-power electricity transformers.
In fact, fluorine is used in many fluorochemicals, including solvents and high-temperature plastics, such as Teflon (poly(tetrafluoroethene), PTFE). Teflon is well known for its non-stick properties and is used in frying pans. It is also used for cable insulation, for plumber’s tape and as the basis of Gore-Tex® (used in waterproof shoes and clothing).
Hydrofluoric acid is used for etching the glass of light bulbs and in similar applications.
CFCs (chloro-fluoro-carbons) were once used as aerosol propellants, refrigerants and for ‘blowing’ expanded polystyrene. However, their inertness meant that, once in the atmosphere, they diffused into the stratosphere and destroyed the Earth’s ozone layer. They are now banned.
