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).
The four best data rich periodic tables on the web: Wikipedia is stuffed full of detailed periodic table data and information; Mark Winter's WebElements has been on the web since 1993 and it is the most data complete PT website out there; Theo Gray's Photographic Periodic Table is the most beautiful periodic table on the web (full of interesting photographs, element curiosities and stories); Michael Dayah's Ptable has lots of cool dynamic interface features:
| 1993 | WebElements: The Periodic Table on The Web |
| 2007 | Gray's Photographic Periodic Table |
| 1997 | Ptable |
| 2001 | Wikipedia Periodic Table |
| Year: 1993 | PT id = 114, Type = data |
WebElements: The Periodic Table on The Web
Mark Winter's WebElements was started in 1993 when it was one of the first websites on the internet.
Mark Leach's Chemogenesis web book uses the WebElements periodic table as its master data source, and it does not attempt to duplicate it.

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. Explore!
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. It is Theo's aim to be the number one periodic table resource on the web.
Mark Leach, the database curator writes:
"I find Theo's website and approach to be complementary to the more academic WebElements."
| Year: 1997 | PT id = 582, Type = data |
Ptable
Ptable is an excellent, data filled, dynamic periodic table with an intuitive and flexible interface, available in 50 languages:
| Year: 2001 | PT id = 1025, Type = data formulation review |
Wikipedia Periodic Table
The Wikipedia Periodic Table pages are astonishing, giving hyper-linked data about:
- Formulations
- History
- Discovery
- Elements
- Isotopes
- Personalities
- Compounds
- etc.
