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.

Bernard Schaeffer's Quantum Mechanics Consistent Periodic Table
My graphic representation of the orbitals needed for the periodic table is without brilliant colors, but much simpler. It shows the nodes of vibration of the spherical resonator (a spherical musical instrument) also called spherical harmonics appearing in the spherical solution of the Schrödinger equation. It may be noticed that the atom is also a spherical resonator, not of sound but of the de Broglie waves.
The spherical harmonics (feminine word in french!) have been discovered by Legendre two centuries ago, see my book. Only the plane nodes of vibration are shown. The nodes of the orbitals are a 3D equivalent of the Chladni figures (also discovered two centuries ago) on a vibrating plate: "Aufbau" with spherical harmonics.
The random electronic exceptions in the subshells don't appear. The spherical nodes of the orbitals are represented only for the s subshells. This is a much simpler representation than the usual 3D representations. It can be used to represent the entire periodic table as I have shown earlier. The elements are in regularly increasing atomic numbers.
