The Fundamental Theory requires neutrons to accumulate within the center of the nucleus, in a highly organized manner, a dense neutron core'. Repulsive protons must remain as far apart from one another as their nucleonic bond with neutrons of the core allow, forming a protonic shell'. Electrons should orbit the individual protonic ligands of a structured nucleus, forming nuclear hydrogen'. These, in turn, can form nuclear covalent bonds', nuclear H2, which we identify as lone pairs' of electrons. The electronic shroud of electrons, therefore, consists of electrons that are localized around the nucleus, in geometrically fixed positions, in degenerate shells, because they are bound to and interacting on a one to one basis with the protons of a structured nucleus. Not only does this picturesque model superimpose itself over the known empirical facts, it explains why one combination of protons and neutrons is stable and abundant, while another is not. Neutron B-decay ratios of unstable nuclei are used to prove' that structured nuclei do exist, in the geometrical manner prescribed.
