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.
H2CO3 is carbonic acid. It is a central Carbon atom with one oxygen double bonded to the carbon and two single oxygen's covalently bonded to the carbon. The two oxygens with t â¦ he single bonds have the hydrogens bonded as well.arbonic acid is a weak acid, and so you might think that there would be nonionized H2CO3 molecules. That simply isn't the case. H2CO3 molecules don't exist in water. (H2CO3 molecules are thought to exist in interstellar space, but not on Earth, and not in water.).
