How many electrons does sulfur have?from geometryofmolecules.com
Here, sulfur forms bonds with four oxygen atoms, which means four electron regions are around it. To accommodate the electrons shared in these bonds, it needs to form 4 hybrid orbitals. As a result, there is a formation of one s-hybrid orbital and three p-hybrid orbitals. ( Each s orbital can accommodate 2 electrons, and p orbital can accommodate 6 electrons). Hence SO42- ion has an sp3 hybridization.
