In the molecule SF6 sulfur hexafluoride , the central atom is sulfur. To determine the hybridization of the central atom, we need to consider the number of electron domains around the sulfur atom.Sulfur has 6 valence electrons, and each fluorine atom contributes 1 electron, making a total of 12 electrons around the sulfur atom. Since there are 6 fluorine atoms bonded to the sulfur atom, there are 6 electron domains 6 single bonds .To accommodate 6 electron domains, the sulfur atom needs to use one s orbital, three p orbitals, and two d orbitals, which results in sp3d2 hybridization. Therefore, the hybridization of the central atom sulfur in the SF6 molecule is sp3d2.
