Nucleus Directs the Electronic Structure of the Atom

The present study supports the provocative idea that the nucleus directs the atom’s electronic structure. With the progress of the atomic number the Atomic Molar Volume evolution of the chemical elements obeys the atom’s electronic structure rules, fitting at the same time the concomitant specular evolution of the Neutron Excess addition to the nuclei. Details such as the Atomic Molar Volume contraction of the d blocks transition metals or of the Eu and Yb atomic volume anomaly of the lanthanoid metals respond to the nuclear in addition to the atom’s electronic structure. Atom’s nuclei are synthetized in the star interior and capture the electrons only after migration to the star’s periphery, to become stable atoms: nuclei are prior to atoms. Nuclear structure elements, like the 50 and 82 neutron and proton magic numbers, are geared to the noble gases, the central elements of the electronic structure.
