I have been researching in this area. I have noted that you can derive
the standard electron shell structures from just the ionization data.
If you goto www.webelements.com, they have a graph showing the amount
of energy required to ionized each electron in the atom. They show up
to 21 ionization energies. I have charted these by looking at the
relative difference between the levels (subtract ajoining values to
find the difference) and charting them on a logarithmic scale which
brings any large differences in energy level into view. What you do
see are distinct energy groupings corresponding to the 2 electrons in
S orbitals, 6 in P orbitals and so on.

See:

http://www.webelements.com/webelements/elements/text/Kr/ionz.html

Tied together, these charts give a continuous view of the energy up to
Krypton. I am still working on the spread*** containing the data,
but I can post it if anyone is interested. Curiously, weblements
doesn't have much data beyond krypton. I was looking for ionziation
data for Xenon and Radon to fill in the rest of the data, but I cannot
find it on the web. Can anyone suggest where I might be able to find
such data?

The data does show anomolies in the energy levels. The P orbitals
appear as a group of 6 electrons with relatively the same energy level
difference, but there is an anomoly in that it could be broken up into
a group of 4 and then the energy level drops significantly, leaving a
group of 2. I am working on my cubic atomic model to help explain
these differences.
