Interesting Facts  When mixed with water, it reacts EXPLOSIVELY.  It must be handled with EXTREME care in a Laboratory.  Has a Strong Characteristic smell.

Physical Properties  Pale; Yellow  Liquid to Solid  Lightest element in Group Halogen/17  occurs naturally in the earth's crust where it can be found in rocks, coal and clay

Chemical Properties GGas to Liquid SStrong odor RReacts at room Temperature ffluorine occurs as a diatomic molecule, F2 FFluorides are released into the air in wind-blown soil.

How its used  Fluorine can also protect us from dental decay, if it is applied through toothpaste twice a day. If fluorine is absorbed too frequently, it can cause teeth decay.  Fluorine gas is released in the industries. This gas is very dangerous, as it can cause death at very high concentrations. At low concentrations it causes eye and nose irritations
