WebFluorine (F) is the heaviest of the halogen elements (Group 17; Group VIIa) and the chemical element with the highest reactivity. Even the noble gases krypton, xenon, and radon can combine with fluorine to produce compounds. Glass, metals, and even water, among other things, will burst into a brilli... Fluorine is used to fluorinate uranium tetrafluoride, itself formed from uranium dioxide and hydrofluoric acid. Fluorine is monoisotopic, so any mass differences between UF 6 molecules are due to the presence of 235 U or 238 U, enabling uranium enrichment via gaseous diffusion or gas centrifuge.
