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).

Rutherford and the Geiger–Marsden Gold Leaf Scattering Experiments
Geiger, H., & Marsden, E. On a Diffuse Reflection of the ?-Particles. Proceedings of the Royal Society A, 82, 495–500 (1909) and Rutherford, E. The Scattering of ? and ? Particles by Matter and the Structure of the Atom. Philosophical Magazine, 21, 669–688 (1911).
"The Rutherford scattering experiments were performed between 1906 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester.
"Experiments showed that every atom had a nucleus where all its positive charge and most of its mass is concentrated. This was deduced this after measuring how a beam of alpha particles is scattered when it strikes gold leaf (thin gold foil)."
