Sulfur in SF 4 is in the formal +4 oxidation state.Of sulfur's total of six valence electrons, two form a lone pair.The structure of SF 4 can therefore be anticipated using the principles of VSEPR theory: it is a see-saw shape, with S at the center.One of the three equatorial positions is occupied by a nonbonding lone pair of electrons. These are arranged in a trigonal bipyramidal shape with 102° F-S-F bond angles between the equatorial fluorine atoms and 173° between the axial fluorine atoms. So let's multiply that out ... six plus twenty eight equals thirty-four total valence electrons. UNII-73U0ARO564. Of hybrid orbitals of S = 4+(2/2)=5. Write Lewis structures for SeF4 and SeF6.
