For H2SO4 we have a total of 32 valence electrons. Put a pair between the atoms. We're forming chemical bonds here. We've used 8, 10, 12, and then around the outside to fill the octets on the Oxygens, 14, and 32.So this looks like a pretty good Lewis structure for H2SO4. In the H 2 SO 4 Lewis structure Sulfur is least electron electronegative atom and goes in the center of the Lewis structure. 2  When we have an H (or H2) in front of a polyatomic molecule (like CO 3, SO 4, NO 2, etc.) we know that it's an acid.
The two available electrons (one from each H atom) in this diagram fill the bonding Ï 1 s molecular orbital. Because the energy of the Ï 1 s molecular orbital is lower than that of the two H 1 s atomic orbitals, the H 2 molecule is more stable (at a lower energy) than the two isolated H atoms.wo electrons each fill the Ï 2 s and Ï2s* orbitals, 2 fill the Ï2pz orbital, 4 fill the two degenerate Ï orbitals, and 4 fill the two degenerate Ï orbitals, for a total of 14 electrons. To determine what type of bonding the molecular orbital approach predicts F 2 to have, we must calculate the bond order.
