INTRODUCTION
Fluorine is the most reactive element found on earth and this makes it very difficult in the preparation and handling of the element.It is a poisnous gas with an irritating smell.
Most metal catch fire in fluorine even inactive metals like gold and plantinum are attacked if heated in a stream of the gas. It combines directly with most elements and indirectly with nitrogen, chlorine, and oxygen.

ECONOMIC IMPORTANCE
* Fluorine and hydrogen fluoride are used to make Uranium hexafluoride which is used in the separation of Uranium isotopes.
* Fluorine has a wide varety use such as a refrigerant,anaesthetic,non-stick agent,insulator and so on.
* Teflon,a fluorine plastic is highly resistant to most chemical action and is widely used to make such products as motor gaskets and dashboard accessories in the automobile
industry. * Tin(II)fluoride is used in many toothpaste to prevent tooth decay.
