Xenon has eight electrons, and four fluorines uses four of them. This means the central atom (xenon) has two lone pairs and four bonds. This translates to a square planar geometry. The square planar molecular geometry in chemistry describes the stereochemistry (spatial arrangement of atoms) that is adopted by certain chemical compounds. As the name suggests, molecules of this geometry have their atoms positioned at the corners of a square on the same plane about a central atom.
