See the answer. The last two electrons exist as a 'lone pair' sitting 'above' the sulphur atom (visualising the molecule like a three-legged stool, the S atom is the 'seat', and the O atoms are the 'legs') It's a similar structure to the ammonia (NH3) molecule, which has a non-bonding 'lone pair' of electrons 'above' the N … This is the simplest explanation of SO3 electron geometry. These assume a tetrahedral geometry, however, one of the arms of the tetrahedron is a lone pair, and geometry descends to trigonal pyramidal with respect to phosphorus. Now if we use a model called the VSEPR, (Valence Shell Electron-Pair Repulsion – a model which is based on the repulsive behavior of electron pairs) we will find out that as all oxygen are spread out, they repel each other, which expect SO3 as nonpolar.
