Fluorine

Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. It is the most electronegative element and the most reactive of all the elements, even reacting with noble gases. Fluorine is commonly found in minerals such as fluorite, and is used in a wide variety of applications including the production of Teflon, fluoridation of water, and in the production of many pharmaceuticals.
