The bound pairs (two C-S bonds) of electrons to the core carbon atom are represented by X. The valence-shell electron-pair repulsion (VSEPR) theory states that electron pairs repel each other whether or not they are in bond pairs or in lone pairs. In addition, the unbonded electrons on the sulfur and oxygen create repulsion between atoms. The valence electrons are those present in the outermost shell of an atom that participates in the bond formation. So each flooring has seven valence electrons.
