The Photographic Periodic Table of the Elements. 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.
Periodic Tables providing data about the chemical elements, rather than novel formulations: Theo Gray's Photographic Periodic Table Theodore Gray's Periodic Table.Com is a live version of what is generally regarded as the most beautiful periodic table to be developed so far. It is a treasure trove of pictures, videos and stories. Theo is an enthusiast and a collector, and he uses the power of Mathematica (he is a co-founder of Wolfram Research) to drive his astonishing website.

Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). 1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion. Therefore, no elements seen as wisps and glints past this point are of consequence. Top of Page KAS Periodic Table The KAS periodic table reproduces and depicts the nuclear properties of chemical elements.
The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. Location that remains near the Neutron Dripline of element. Read more here, here and here. Sensu or Fan Periodic Table By NAWA, Nagayasu – A Japanese schoolteacher and periodic table designer – a "Sensu" or fan periodic table: The Nuclear Wall Chart. Origin of the Periodic Table. I know what the periodic table looks like, but where did it come from?
Whose idea was it to arrange the elements this way? He set them out in order of atomic weight, and then grouped them into rows and columns based on their chemical and physical properties. 1869...that's way before the Schrödinger model, or even the Rutherford model. That's right. Mendeleev had no idea what atoms were made of or why they behaved as they did. Based on the gaps in his table, Mendeleev even succeeded in predicting the existence and properties of several new elements. That's pretty impressive. His basic rule was this: the elements in any column, or group, of the table are similar to their column-mates.

UPDATE #2: NEW! Periodic Table of Criminal Elements. I need your help because my ideas are drying up.
This is what I have so far and I’ve thought of about a dozen more to add that I can think of including the SCOTUS judges, and usual rabble of right wing talking heads. I need help identifying the lying and corrupt politicians, blowhards and business execs that destroy America. Also if you have some creative names that would be appreciated. Don’t worry about the formatting I’ll do that last. Here is what I have so far on paper. I was browsing some old pictures to download to my phone and I came across one of the funniest and most poignant images I came across during the election.
