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.
