WebJan 30, 2024 · A fluorine atom has an electronic structure of 1s 2 2s 2 2px 2 2py 2 2pz 1. It has 9 protons in the nucleus.The incoming electron enters the 2-level, and is screened from the nucleus by the two 1s 2 electrons. It therefore feels a net attraction from the nucleus of 7+ (9 protons less the 2 screening electrons). 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.
