Fluorine

Welcome to the page of __**Fluorine**__. Fluorine came from the Latin and French words for flow, and fluere. Henrie Moissan discoverd it in 1886. He earned the 1906 Nobel prize in chemristy.

 * ==== Fluorine is the most reactive of all elements and no chemical substance is capable of freeing fluorine from any. For this reason, fluorine does not occur free in nature and was extremely difficult for scientists to isolate. ====
 * ==== The first recorded use of a fluorine compound dates to around 1670 to a set of instructions for etching glass that called for Bohemian emerald (CaF 2 ). Chemists attempted to identify the material that was capable of etching glass and George Gore was able to produce a small amount of fluorine through an electrolytic process in 1869. ====
 * ==== Moissan, a French chemist, was the first to successfully isolate fluorine in 1886. He did this through the electrolysis of potassium fluoride (KF) and hydrofluoric acid (HF). He also completely isolated the fluorine gas from the hydrogen gas and he built his electrolysis device completely from pla tinum. His work was so impressive that he was awarded the Nobel Prize for chemistry in 1906. Today, fluorine is still produced through the electrolysis of potassium fluoride and hydrofluoric acid as well as through the electrolysis of molte While fluorine is not an essential nutrients for plants or animals, it can help prevent tooth decay. ====




 * ====== Pure fluorine gas is obtained by the electrolysis of hydrogen fluoride in the presence of potassium fluoride. Hydrogen gas is also formed by this process.About one-fifth (20%) of pharmaceutical drugs contain fluorine. ======
 * ==== Fluorine is incredibly reactive! It reacts explosively with hydrogen even in dark, cool conditions. Metals, water and most other substances burn with a very bright flame in a stream of fluorine gas. ====
 * ==== Only one isotope of fluorine is stable (fluorine-19). All others are radioactive and have very small half-lives. ====
