In Xenon hexafluoride, Xe has 8 valence electrons and 6 monovalent atoms. According to VSEPR theory, the repulsion between the lone pairs is minimized…. It consists of 6 bond pairs and one lone pair. The XeF4 has a solid white appearance and … I believe this is due to the fact that AsCl 5 has a trigonal bypyramidal shape, and all of the "outside" atoms i.e the 5 Cl atoms bonded to the central As atom, are the same, so the dipole moments of each of these molecules are equal, and cancel each other out, making the molecule non-polar. Xenon from group 0 has eight electrons in its outer shell and each fluorine provides one for the bond maing a total of 8 + 6=14 electrons. VSEPR suggests PBP(Pentagonal Bipyramidal) geometry , but by electron diffraction experiments it is said to have “Octahedral” geometry with Fluorine atom on the corners. Some xenon hexafluoride, XeF 6, is also produced, and this production is increased with an increased fluorine concentration in the input mixture. Learn more.
