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 57.38 -1 [Ar].3d10.4s2.4p6
Sn 42.62 2 [Kr].4d10.5s2
