In sulfur hexafluoride SF6 , 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 + number of monovalent atoms - charge Sulfur has 6 valence electrons, and there are 6 monovalent fluorine atoms. The molecule is neutral, so the charge is 0. 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.
