Because each different isotope produces decay particles with a different energy, those with the greatest energy will have the greatest radius. Those with less energy will have a smaller radius. This leads to a series of concentric shells. Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
