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 formula of sulphate is SO4 2- this means the total answer has to add up to minus two. We want S so O stays constant gaining the oxidation number from O from the periodic table. The oxidation number for oxygen is -2, requiring 2 electrons to fill its outer shell. this will determine the oxidation state for Sulfur.eport Abuse. In the sulfate ion, SO42-, the oxidation numbers of the sulfur and the oxygens add up to 2-. The oxygens are 2- each, and the sulfur is 6+. Uzaam (OÑCA) Â· 2 years ago.
