The atomic nucleus model was developed to clarify the revised table of elements. Between lutetium and hafnium, the difference in atomic masses does not reach four units, while new elements with atomic numbers 72-75 are located there. How can nucleons be packed in a nucleus so that it is droplet and shell and with the required number of neutrons? Such a nucleus is obtained if alpha particles are placed in the surface layer, and only neutrons are inside the nucleus. In this case, for new chemical elements with numbers 72-75 inside the nucleus, the neutron can be replaced by a proton, and therefore the atomic mass of the elements between lutetium and hafnium will change insignificantly. The model was obtained by considering the structures of atomic nuclei from heavy to light.
