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|
| F|| 28.32||-1||[He].2s2.2p6|
| Nd|| 71.68||3||[Xe].4f3|
