Evidences from physics and chemistry implies that atoms likely can gradually grow out, on their core (Z ＝ 1-2 that will expand in Z ＝ 27-28 and 45-46), vertical 4 a (Z ≧ 1, representative), 4 b (Z ≧ 21, transition), and 8 c (Z ≧ 57, inner transition) alpha clusters bonding with valence neutrons that electron and proton distributions seem similar — all of electrons of inner shells following protons in nuclei, which means that most of atomic space was occupied by electrons of outermost shell only and experimental results of Geiger and Moseley could not completely exclude a possibility that atomic nuclei contain electrons. In other words, atomic structures — foldable — corresponded to Thomson’s model, but distributing distances of outer and inner electrons were very different, not uniform as in Rutherford’s model to some degree, which could pave a promising way to clarify or integrate structures of atoms and atomic nuclei.
