Perodic Table Information

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
Hg	71.75	2	[Xe].4f¹⁴.5d¹⁰
Se	28.25	-2	[Ar].3d¹⁰.4s².4p⁶
