WebIt is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes. Atoms of the same element with different numbers of neutrons. Key for isotopes WebAnswer: Molecules made of more than one type of covalently bonded nonmetal atoms, like carbon dioxide gas (CO2), remain nonpolar if they are symmetrical or if their atoms have relatively equal pull. Even large compounds like hexane gasoline (C6H14), is symmetrical and nonpolar. 28.
