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.
Because the H 2 molecule has two electrons, they can both go in the bonding orbital, making the system lower in energy (and, hence, more stable) than two free hydrogen atoms. This is called a covalent bond.ecause the H 2 molecule has two electrons, they can both go in the bonding orbital, making the system lower in energy (and, hence, more stable) than two free hydrogen atoms.
