The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
Various Periodic Tables
As discussed on this page of the Chemogenesis webbook, the periodic table is ambiguous as to what it is showing.
Does the PT show the element as the abstract 'basic substance', or gas phase atoms or the material substance?
