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.

Chemical Thesaurus Reaction Chemistry Database Periodic Table

A periodic table front end to the Chemical Thesaurus Reaction Chemistry Database Periodic Table. Clicking on an element gives access to database searches of chemical species and their interactions.

A quote neatly sums up what the ChemThes reaction chemistry database project is trying to achieve:

"The Chemical Thesaurus is a reaction chemistry information system that extends traditional references by providing hyperlinks between related information. The program goes a long way toward meeting its ambitious goal of creating a nonlinear reference for reaction information. With its built-in connections, organizing themes, and multiple ways to sort and view data, The Chemical Thesaurus is much greater than the sum of the data in its database.

"The program does an excellent job of removing the artificial barriers between different subdisciplinary areas of chemistry by presenting a unified vision of inorganic and organic reaction chemistry."

Rogue Elements: What's Wrong with the Periodic Table

An article in New Scientist by Celeste Biever (news editor at Nature), Image by Martin Reznik

Weights gone awry, elements changing position, the ructions of relativity – chemistry's iconic chart is far from stable, and no one knows where it will end

IF IMITATION is the sincerest form of flattery, the periodic table has many true admirers. Typefaces, types of meat and even the Muppets have been ordered in its image. For chemists, knowing an element's position in the periodic table, and the company it keeps, is still the most reliable indicator of its properties – and a precious guide in the search for new substances. "It rivals Darwin's Origin of Species in terms of the impact of bringing order out of chaos," says Peter Edwards of the University of Oxford.

The origins of the periodic table lie in the 19th century, when chemists noticed that patterns began to emerge among the known chemical elements when they... click here to continue:

Zambon's Periodic Table Based on Triads

Alfio Zambon – Universidad Nacional de la Patagonia

1. Introduction

In the last decades, the notion of triad has been recovered by Eric Scerri, who suggested it as a possible categorical criterion to represent chemical periodicity. In particular, he reformulates the notion of triad in terms of atomic number instead of atomic weights and, in this way, the value of the intermediate term of the triad is the exact average of the values of the two extremes. The author notes that the attempt of finding new triads is very important since this relation is based exclusively on the atomic number, that is, the only feature of the elements considered as basic substances. In this work, I will follow Scerri's general proposal.
