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 30.88 -1 [Ne].3s2.3p6
U 69.12 3 [Rn].5f3
