Element analysis and oxidation numbersFor each compound, and where possible, a formal oxidation number for each element is given, but the usefulness of this number is limited, especially so for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. | Element | % | Formal oxidation state | Formal electronic configuration |
