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.
RSC Visual Elements Periodic Table: Alchemy
From the RSC Website: "Alchemists are often described as the first chemists. They developed an extraordinary language (rather than the chemical symbols we use today) to describe all manner of things, from chemical reactions to philosophical tenets. Click on ‘What is Alchemy?’ to learn about the three aims of the alchemists. Click on each of the alchemical symbols for more information and to see alternative symbols."
