The INTERNET Database of Periodic Tables
There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).

Elemental Oxidation States Periodic Table
The periodic table of fluorides (mainly) shows the range of possible oxidation states. Note that lithium, by way of example, is deemed to have two oxidation states: Li0 (the metal), and Li+ (the lithium ion):
There are a few exceptions and points to note:
- There is a general increase in the number of possible oxidation states towards the lower right hand side of the periodic table.
- Nitrogen(V) fluoride, NF5, is not known, but the nitrogen(V) oxide is: N2O5.
- PtBr2 and PtBr3 are known, but PtF2 and PtF3 are not.
- All elements are known in the zero oxidation state, but apart from: He, Ne & Ar, and these are not shown in the diagram below.
- All data is from WebElements.
