Let's be just a little bit careful here. While I agree 100% with your conclusions, radioactive isotopes have nothing to do with electron shells.
I know that, I was just drawing an analogy. Unstable isotopes are unstable because there's a lower-energy state available to them, which they decay into. Excited electrons do the same thing (though usually on a faster time scale): they decay from excited states to lower-energy states. The details of the interaction don't really matter for that basic principle. If what we consider the ground state was not the true ground state, then there would be similar decays from the fake ground state to the true ground state, but there aren't. That's my only point.
