Internet Database of Periodic Tables
There are thousands 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.

Dash's Quantum Table of the Periodic System of Elements
Harriman H. Dash, A quantum table of the periodic system of elements, International Journal of Quantum Chemistry, vol. 3, no. S3A, supplement: Proceedings of the International Symposium on Atomic, Molecular, and Solid?state Theory and Quantum Biology, 13/18 January 1969, pp. 335–340.
The abstract reads:
"The shortcomings of the long form of the periodic table of the chemical elements and the evident need for updating this format are briefly reviewed. To the question 'what format?' quantum physics provides an unequivocal answer. The foundations for the design of a quantum table are outlined. These are based on the principal quantum number as derived from the Schroedinger wave equation, the law of second order constant energy differences, and the coulomb–momentum interaction. These concepts are all combined into a single format which optimally and explicitly relates periodicity to atomic structure and the physical, chemical, and biological properties of the elements. This relationship emphasizes the unity and universality of all sciences."
