WebAug 15, 2024 · Jim Clark. Truro School in Cornwall. This page explains the relationship between the physical properties of the oxides of Period 3 elements and their structures … WebThe oxidation state of an atom is a measure of the degree of oxidation of an atom. It 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
