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).

Periodic Tables from the year 2007 :

Awesoments

"In the 300 B.C., years before the birth of black Jesus, Aristole postulated that all good things were made of 'win'. That was a pretty good guess, but he was drunk and probably also having an orgy. Modern day awesominers know there are actually 118 fundamental 'awesoments' that compose all good things. The Periodic Table of Awesoments can be a very useful tool. It's designed to show the relationships between awesoments, and often one can even predict how awesoments interact simply by their positions on the table.":

Second Life Periodic Table

From the Useful Chemistry blog: "Further adding to the set of chemistry tools in Second Life, Hiro Sheridan has created a 3D periodic table with rotating atoms. Although not directly proportional, the relative sizes of the spheres are in the correct order. Clicking on them provides basic information about the corresponding element. The 3D periodic table is available on the Chemistry Corner on Drexel Island."

Canadian Periodic Table

This Canadian PT has lots of subtle Canadian references (apparently) from here.

Rap Periodic Table by NOVI NOV

"I infused the Periodic Table into a rap. It was for an old mixtape. I used to record all my music through my camcorder and would delete the video...and mix just the vocals. I kept some of those video files...enjoy"

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."

Scoville Unit Periodic Table

Welcome to The Scoville Food Institute, the home of Scoville Foods Hot Sauce.

Here at The Scoville Food Institute, our main focus is making REALLY GREAT hot sauce. All day long, we study the chemistry of hot peppers and try to come up with new, flavorful hot sauces. We'll add a dab of this and a smidgen of that, all the while staying away from additives, preservatives, MSG, and other nasty/non-essential ingredients.

University of Jaén (Spain) Wall Mural Periodic Table

From November of 2007 a large Periodic Table placed on the main facade of Sciences Building in the University of Jaén (Spain) welcome everybody.

The table was made in honor of Mendeleev on the 100 aniversary of his death and on the occasion of the Spanish Year of Science according to the concept and design of the Spanish Chemist Antonio Marchal Ingrain, who was inspired in a postage stamp launched that year in Spain.

The artistic mural is composed of 117 tiles of 20 x 30 cm, one for each of the elements known to date, reaching a final dimensions of 2.8 x 3.6 meters. Apart from the traditional information with which students are familiar, such as the atomic number, atomic mass and the chemical symbol of the element, each of the ceramics incorporate information concerning the meaning of its name in Latin or Greek, the year and the name of the person or group of people who discovered it or isolated.

Dr. Antonio Marchal, UNIVERSITY OF JAÉN, SPAIN

Freaky Trigger Periodic Table

The Freaky Trigger Periodic Table. "What the FreakyTrigger periodic table is not: science - not even in the loosest limbed definition that FT uses (ie thought experiments and puns). It is not a way of ordering the world, the makers of the desert periodic table put up last week would be quite disappointed by the general lack of periodicity. Whilst there may be some serendipity in the periodic placement of some of the "elements", this is more by accident than by design. Indeed the design merely fits that of the periodic table because that was the idea in the first place. And as the methodology shows, any over-arching idea to create a consistent cosmology out of this project was soon scuppered by the organic scourge of many bright ideas. Alcohol.":

Extending the Periodic Table

The periodic table now extends to element 118, Oganesson, and scientists are attempting to go further. Below is part of a Segre chart, proton number on the y-axis and neutron number of the x-axis, from a report from the Japanese Superheavy Element Laboratory, RIKEN Nishina Center, RIKEN.

The diagram shows various nuclear reactions, for example: ²³²Th + ⁴⁰Ar to make ²⁷²Hs.

Bent & Weinhold's 2D/3D Periodic Tables

From a paper by Henry Bent & Frank Weinhold, J. Chem. Educ., 2007, 84, 7, 1145 and here. The authors write in the abstract:

"The periodic table epitomizes chemistry, and evolving representations of chemical periodicity should reflect the ongoing advances in chemical understanding. In this respect, the traditional Mendeleev-style table appears sub-optimal for describing a variety of important higher-order periodicity patterns that have become apparent in the post-Mendeleevian quantal era. In this paper we analyze the rigorous mathematical origins of chemical periodicity in terms of the quantal nodal features of atomic valence orbitals, and we propose a variety of alternative 2D/3D display symbols, tables, and models.":

Hardware, Periodic Table of

From This Into That – by Jim Rosenau – comes a Periodic Table of Hardware that rather cleverly uses the usual element symbols:

• H for hammer
• He for hedge shears
• Li for light bulb

Orthogonal Dimension Periodic Table

Novel Visualization of the Periodic System of Elements. The Orthogonal Dimension. Click here to read the paper.

ABSTRACT: The Periodic system of elements is presented in a novel way such that rare earth and actinides, and the triads Fe/Co/Ni, Ru/Rh/Pd, Os/Ir/Pt, and Hs/Mt/Uun, are shown orthogonal within the table, and not separately as accompanying rows. The new graphic presentation facilitates the visual orientation, eliminates the now prevailing crunching of the elements in the middle of the table, and avoids the cognitive confusion of scattered positioning of the <<a>> and <<b>> element subgroups sometimes widely separated within the same row. A characteristic meandering pattern emerges whenever switch occurs between the horizontal and orthogonal dimension of the Periodic system; the inner meaning of these switches remains to be elucidated.

Seeger-Quadbeck Periodic Table

Seeger-Quadbeck H-J 2007, World of the Elements Elements of the World, Wiley-VCH, Wienheim, inside cover.

René Vernon, who provided the graphic, writes:

"An example of a rarely seen 32-column table. The categorisation scheme is interesting.

• Hydrogen is a category of its own.
• The semimetals include selenium and astatine.
• There is no separate category for the halogen nonmetals.
• On page 100 the author refers to the inner occupation of the TM and Ln/An being particularly clear."

Distribuzione Peridica Degli Elemnti

Distribuzione Peridica Degli Elemnti – Periodic Distribution of Elements – by Leonello Paoloni.

From La Chimica nella Scuola, Sept. 2007, pp 111.

"Fig. 2. The periodic distribution of elements correlates with the group distribution of atomic electrons. Groups are formed so that all elements of the same family are found in corresponding positions (for example, the halogens are always in the second-to-last position in a group of six elements)." (Google Translate)
