Correct charges of all nuclei of all chemical elements. The charge of the nucleus of an atom is the main property of a chemical element.
The model of the atomic nucleus was developed in order to explain the corrected 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 placed there. How can you pack nucleons in a nucleus so that it is drop and shell and with the right amount of neutrons? Such a nucleus is obtained if alpha particles are placed in the surface layer, and only neutrons are placed 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.
I have the elements distributed in the long-period version of the table according to the charges of the nuclei so as to fill all the cells of the table And how to distribute the isotopes of atoms according to the charge of the nuclei in the table. isotopes could be placed to the right and left of the element in a table that would turn from a flat one into a volumetric one ... on the right, for example, with a larger number of neutrons and on the left with a smaller one ... and a certain body would be obtained from all elements and their isotopes ...
