Element analysis and oxidation numbers
For 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 |
| Cl | 42.68 | -1 | [Ne].3s2.3p6 |
| U | 57.32 | 5 | [Rn].5f1 |
