Give the formula of a polyatomic ion that you would expect to have the same Lewis Structure as A. Cl2 B.H2SO4 C.CH4 D.GeCl4 If you're going to answer: "Cl2 is one of the seven diatomic elements H2SO4 is sulfuric acid and has the sulfate ion with neg 2 charge CH4 is a methane molecule is organic and covalent GeCl4 Germanium tetrachloride which is ionic" please explain what you mean because I really need to understand! thank you very much!
