Atomic electrons spr
The currently accepted atomic model (nucleus + electron cloud) assumes
that every electron that can be ejected from a ground state atom or
atomic ion in any low energy collision with an atom, ion or particle
exists as an electron in that ground state. There would seem to be no
way in which this assumption can ever be tested by experiment.
How about using x-ray scattering to determine the charge distribution
of an atom at any given level of ionization? The spread of the charge
distribution of a nucleus is known to be much smaller (about 10^5
times smaller) than the spread of the charge distribution of an atomic
electron. So, if I understand correctly the assumption you are talking
about, it's certainly experimentally testable.
Google "x-ray scattering" or "x-ray spectroscopy". Computational
chemistry is a major industry, with electronic structure calculation
as one of its main goals. They wouldn't get very far if they couldn't
compare their calculations to experiments.
