The electro-magnetic force cannot be used as an explanation for why

of a shell goes undefined.

Bull****--it's not dedefined. The shells are equipotential
supersurfaces of quasiplanar orbits which behave otherwise as regular
macroscopic orbits of heavenly bodies but under a nonsaturated
elèctric potential. The s-shell elèctròn dives intom the nucleus; the
p-shell and further elèctròns make whorls about the nucleus as in a
spirograph, where the p-shell is commensurate with the linear
polarisation in a dipolar antenna. These whorls would also be
apparent in gravital orbits if their gravitomagnetic (a misnomer in
itself) potential were as strong in relation to their bodies' size.
Indeed, the planets do whorl about [weakly] over thousands of years by
libration and nutation from outside and inside tidal forses. In a
many-body sustem, Kepler's law of planar orbits goes out the window.
