Fluorine is in the [[halogens]] group. The [[atomic mass]] is 18.9984 g/mol. The natural phase of Fluorine is gas. Fluorine's [[Electron configuration]] is 1s<sup>2</sup> 2s<sup>2</sup> 2p<sup>2</sup>. The melting point of Fluorine is -219.62℃ and the boiling point is -188℃. The temperture of Fluorine is low, it becomes colorlessnessly. | Fluorine is in the [[halogens]] group. The [[atomic mass]] is 18.9984 g/mol. The natural phase of Fluorine is gas.

The temperture of Fluorine is low, it becomes colorlessnessly. Fluorine is the most electronegative element on the periodic table, so it can be easily combined with any other element and when the temperture becomes high, it reacts stongly. In addition, because it is highly reactive, it also can react with [[hydrogen]]. The reaction can be explosive. The reaction is very dangerous especially with [[water]].

Because of the special properties of Fluorine, it can be used for many purposes. Fluorine is excellent against the tooth decay. Fluoride covers teeth with thin layers, so it protects from forming cavities. In addition, many nations add Fluorine into the city water for disinfection. Crystals of calcium fluoride (CaF2), also known as fluorite and fluorspar, are used to make lenses to focus infrared light. Fluorine is also used in the manufacture of Freon, which is used in the refrigerator. Unfortunately, freon fills the air with pollutants, and eats the [[Ozone]] layer.[http:// | Because of the special properties of Fluorine, it can be used for many purposes.
