In SF6 sulfur hexafluoride , the central sulfur atom is surrounded by six fluorine atoms. To determine the hybridization of the central atom, we can use the following formula:Hybridization = 1/2 number of valence electrons on the central atom + number of atoms bonded to the central atom - charge on the central atom Sulfur has 6 valence electrons, and it is bonded to 6 fluorine atoms. The molecule is neutral, so there is no charge on the central atom. Plugging these values into the formula:Hybridization = 1/2 6 + 6 - 0 = 1/2 12 = 6Since the hybridization value is 6, the central sulfur atom in SF6 is spd hybridized. This means that the sulfur atom uses one s, three p, and two d orbitals to form six equivalent hybrid orbitals, which are used to bond with the six fluorine atoms.
