Fluorine

Fluorine is the chemical element with atomic number 9, represented by the symbol F. It is the lightest element of the halogen column of the periodic table and has a single stable isotope, fluorine-19. At standard pressure and temperature, fluorine is a pale yellow gas composed of diatomic molecules, F2. In stars, fluorine is rare compared to other light elements. In Earth's crust, fluorine is more common, being the thirteenth most abundant elemen... More
