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 |
Br | 50.18 | -1 | [Ar].3d10.4s2.4p6 |
U | 49.82 | 3 | [Rn].5f3 |
