What is the Periodic Table Showing?

Periodicity

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).

Use the drop menus or search box (below) to Select or Search the 1400 entries in the database:

Periodic Tables from the year 1914 :

1914	Hackh's Periodic Table
1914	Oddo-Harkins Rule

Year: 1914

PT id = 23, Type = formulation spiral

Hackh's Spiral Periodic Table

Ingo Hackh's spiral periodic table of 1914, from Das Synthetisches System der Atome, Hamburg, Hephaestos.

Philip Stewart says:

"I believe that Hackh's 1914 spiral is of special interest it is the first spiral to take account of Mosley's atomic numbers, and the first to show successively larger pairs of coils. It is also interesting because H stands alone in the centre. I have only seen Mazurs' redrawn (as usual!) version, but Mazurs gives SciAm Supplement 1919 as one reference."

This is the Mazurs version:

Year: 1914

PT id = 687, Type = Data

Oddo-Harkins Rule

The Oddo-Harkins rule holds that elements with an even atomic number (such as carbon) are more common than elements with an odd atomic number (such as nitrogen). This effect on the abundance of the chemical elements was first reported by Giuseppe Oddo in 1914 and William Draper Harkins in 1917. See the Wikipedia page:
