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.

Courtines' A Model of the Periodic Table or Periodic Classification

Published in J. Chem. Ed., 2, 2, 107-109 in 1925 by M. Courtines of the Laboratory of Experimental Physics, College of France, Paris.

We do not know the date of the forth image (below), but it looks as if it was prepared a few years later. However, it is a 'top down' view of the 3D formulation.

Lindsay's Periodic Table

From Geoffrey Lindsay:

"I put together a table of elements that may be useful for teaching 101 chem from the point of view of valence electrons and the energy sublevels of the valence orbitals".

Samuel Ruben Periodic Table

An interesting periodic table from 1964, found at an estate sale. The text says that the elements are: "arranged according to the atomic number Z and column relation to the rare gases", and is by Samuel Ruben (wikipedia).

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. Ergo, the bizarre stability of Dubnium 270.

2) This common structure is divided up by the exact same divisors as are the electron orbitals - i.e. the prime numbers of 2, 3, 5, and 7.

3) Pi as a divisor produces its own, unique and dominating organizational patterns.

4) Each of these sets of plotted nuclide "boxes" use identical formats, but are arranged in vertical columns based on the set of 270 AMUs being divided by these prime numbers. So the 5D Table is 270/5 or 54 AMUs per vertical column/"tower".

5) Each system reinforces unique elemental parameters. The system based on 3/Pi, and its second "harmonic" at 6/2Pi reflects physical properties. The 2Pi configuration almost exactly emulates the "conventional" / Mendeleevian element-based table, except the periods are based upon mass not element count, and these periods do not organize in rows of 18 elements, but rather rows of 44 mass units. The organization/configuration of this default structure is: Pi(Pi^2 + Pi + 1) = 44 This is the primary physical default structure of the periodic table and spectrum of elements, as projected in 3D space, and as perceptible to humans.

6) 5D determines everything with magnetic properties. This disproves every single theory that attributes electron shell behavior as determining magnetic parameters. Clearly here we see that the nucleus is "calling the shots", with electron orbitals conforming as driven. The various red and blue shaded boxes are found at extremes of top and bottom.

7) The system of 7D determines most of all physical parameters of surface and molecular behavior. Here we see surface tension, density, softness and hardness, malleability, boiling and melting points and a few other behaviors. This system of correlation is fully unknown to conventional theory. Notice how superlative parameters bunch at the top and bottom of this configuration.

8) When this system of 270 mass units is divided by 12, for 22 mass units per period, the periodic cycle rate precisely correlates with known Type 1 and 2 elemental superconductors. The physical correlations between periodic repetition at 22 mass units, the 270 count system, and superconductors is also completely novel and not compatible to conventional BCS theory. The correlation between this 22 count system and the three largest cross section nuclides known to man (113Cd, 157Gd and 135Xe) is also completely heretical, however mathematically symmetrical and perfect it may actually be organized.

9) The center portion of this common 270 count structure is named the "Cordillera", for the habit of multiple parallel mountain ridges sharing a common alignment. This area is profoundly affected by Pi-based organizations. The very center at 135Xe indicates that the overall table should terminate at element 108 Hassium at 270 mass units. This has a Proton/Neutron ratio of 3:2. This actual nuclide has very poor stability, unlike Dubnium 105 with 270 mass counts. This nuclide has a ratio of precisely 1:Pi/2, indicating the entire table describes a spectrum of mass organizational states spanning the integer ratio of 1:1 (Deuterium) to 3:2, then on through to 1:Pi/2. Current accepted atomic theories concerning "Islands of Stability" are ridiculous.

KAS Periodic Table

The KAS periodic table reproduces and depicts the nuclear properties of chemical elements. This periodic table depicts not only the trends of nuclear properties, but also reproduces their numerical values that remain very close to the experimental values (difference less than 4%).

The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. It is like a library of nuclei and shows the recorded data only. The Segre Chart can not work when the number of neutrons is not given. But KAS Periodic Table works when the number of neutrons is not given.It does not require the number of neutrons to produce the results.This is a simple chart based on the number of protons of chemical element. We identify the following properties of elements:-

  • Location that remains near the Neutron Dripline of element.
  • Location that remains very close to stable or long-lived isotopes of the element. Location that remains near the Proton Dripline of element.
  • In the case of superheavy elements, we identify which Compound Nuclei are involved in the Hot Fusion reaction and which Compound Nuclei are involved in the Cold Fusion reaction.
  • We see the r-process path and assess the r-process abundance.
  • The pattern of abundance of chemical elements.
  • We identify which elements are the product of exothermal fusion.
  • We identify the location of isotope on the basis of two-neutron separation energy.
  • Nuclear binding energy trend. Beta decay trend.
  • We see the Straight Line of Nuclear Stability.
  • Empirical Law discovered.
  • Periodicity in the nuclear properties.
  • We can compare the nuclear properties of an element with the nuclear properties of almost all the chemical elements.
