 * Fluorine is very reactive to nature therefore it is used in rocket fuels, it is also used for burning other materials.****


 * there are other flurine compounds which is used in toothpaste.****
 * the aerosol sprays, cleaning agents and complex polymers are also produced by using fluorine.****
 * **used in some public water facilties to stop people have tooth decay.If someone was to sniff fluorine one would never smell again and would slowly die...****

poisonous gaseous halogen, it is pale yellow-green and it is the most chemically reactive and electronegative of all the element.
 * It is so reactive that glass, metals and even water as well as other substances burn with a bright flame in a jet of fluorine gas.**
 * at high concentration it can cause death and in low concentration it causes eye and nose irritations. Fluorine can become very attached to soil particles.**
