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.

Elsevier's Periodic Table of the Elements

Prepared by P. Lof is Elsevier's Periodic Table of the Elements.

This educational wall chart features the periodic table of the elements supported by a wealth of chemical, physical, thermodynamical, geochemical and radiochemical data laid down in numerous colourful graphs, plots, figures and tables. The most important chemical and physical properties of the elements can be found - without turning a page.

All properties are presented in the form of tables or graphs. More than 40 properties are given, ranging from melting point and heat capacity to atomic radius, nuclear spin, electrical resistivity and abundance in the solar system. Sixteen of the most important properties are colour coded, so that they may be followed through the periodic system at a glance. Twelve properties have been selected to illustrate periodicity, while separate plots illustrate the relation between properties. In addition, there are special sections dealing with units, fundamental constants and particles, radioisotopes, the Aufbau principle, etc. All data on the chart are fully referenced, and S.I. units are used throughout.

Designed specifically for university and college undergraduates and high school students, "Elsevier's Periodic Table of the Elements" will also be of practical value to professionals in the fields of fundamental and applied physical sciences and technology. The wall chart is ideally suited for self-study and may be used as a complementary reference for textbook study and exam preparation.

Step-Pyramid Form of the Periodic Chart

By Bill (William) Jensen, a Step-Pyramid form of the periodic chart.

This formulation is an updated version of the charts by Thomsen (1895) and Bohr (1922) with more elements, including placeholders up to 118, electronic configuration lables, etc. Read more on the Science History Institute website.

Variation of Orbital Radii with Atomic Number

From Jour. Fac. Sci., Hokkaido Univ., Ser. IV. vol. 22, no. 2, Aug., 1987, pp. 357-385, The Connection Between the Properties of Elements and Compounds; Mineralogical-Crystallochemical Classification of Elements by Alexander A. Godovikov & Yu Hariya.

The analyses of the variations of the orbital atomic radii values (rorb) with the increase of the atomic number (Z) allow establishment of the following recurring regularities of their change:

Mineralogical-Crystallochemical Classification of Elements

From Jour. Fac. Sci., Hokkaido Univ., Ser. IV. vol. 22, no. 2, Aug., 1987, pp. 357-385, The Connection Between the Properties of Elements and Compounds; Mineralogical-Crystallochemical Classification of Elements by Alexander A. Godovikov & Yu Hariya.

Any mineralogical-crystallochemical classification of elements must provide answers to the following queries:

  1. Which type of compounds certain elements will prefer to form under given conditions of mineral genesis (elementary substance, chalcogenide, oxide, oxysalt, etc.,)
  2. Whether the element will play a role of a cation or anion of a certain valency
  3. Which type of chemical bond the resulting mineral compound will have
