The final version of the table of chemical elements. The innovation of this work is that in the table of elements, constructed according to Mendeleev’s law and Van den Broek’s rule, new chemical elements with atomic numbers 72-75 and 108-111 are presumably identified, and it is also shown that for heavy elements, starting With hafnium, the nuclei of atoms contain a larger number of protons than is generally accepted.
A model has been developed, a model of the atomic nucleus, that explains the ratio of the number of protons to the number of neutrons.
All table cells are filled. If this table takes place, then I would like to call the groups of elements with numbers 72-75 and 108-111 islands of Filipenko G.G.
About Mendeleev's periodic table of elements.
Dmitry Ivanovich built a table according to atomic weight, and he was right, because. atomic weight characterized the element completely, so to speak. This characteristic implicitly included both the periodicity and charge of the nucleus.
Dmitry Ivanovich did not have time to complete his table. But his constructions were correct, so he placed cerium after lanthanum. This can be seen on a house on Moskovsky Prospekt near the Tekhnologichesky Institute metro station. And someone placed the lanthanides and actinides at the bottom of the table and thus crumpled the table of elements. Who placed the lanthanides and actinides under the periodic table? The era of quantum mechanics has arrived, which includes the periodicity of elements. However, later, the charge of the nucleus of its atom was still accepted as the main property of an element. Why not build a table according to the charges of atomic nuclei, taking into account both atomic weight and periodicity of properties.
Has the periodic table been proven to be absolutely correct or is it correct with some exceptions?
James Chadwick must have made a mistake when measuring the charges of atomic nuclei.
More precisely, not an error in the measurements, but in the fact that I agreed with the table and the result obtained for platinum 77.6 was interpreted as a nuclear charge equal to 78, according to the table.
For copper, the result was 29.3 - more than the true one by 0.3, for silver 46.3 already less than the true one by 0.7, and for platinum less than the “true” one by only 0.6. The decrease is due to protons shielding each other during measurements. Therefore, for platinum with a charge of 78, the result should have been less than what was obtained, or in other words, the platinum atom has a nuclear charge greater than 78 and equal to 82. We build a table of elements according to the charges of the nuclei of atoms of chemical elements. If we assume that in the periodic table of elements the atomic weight increases more or less evenly from left to right and from top to bottom, then the hafnium atom and the ones following it should not be placed immediately after lanthanum - they should be located a line below... This led me in 1989 to building a physical table of elements. Please see this table online.
After lanthanum, I placed the lanthanides so that the line would not be empty, then I placed the light elements in a line and saw that a table of elements was obtained according to the charges of the atomic nuclei. The main property of a chemical element is not periodicity, but the charge of the nucleus. When 71 elements were located in the table without missing cells, I assumed that there should be no open elements 72-75, and the charges of hafnium nuclei and the elements following it should be 4 units greater. Four more protons and at the same time 4 fewer neutrons. I can only guess that the seventy-second electron of element 72 must be located at lower levels compared to the outer ones, since the seventy-second proton replaces the neutron inside the nucleus. Based on my constructions. Therefore, the chemical properties of elements 72-75 will be the same as those of lutetium. In hafnium and the elements following it, the nuclear charge increases by 4 units. It is interesting to look at the decay curve of uranium into fragments. Uranium 92 decays into barium and krypton. From uranium 96 you can derive the same barium and zirconium or lanthanum and yttrium, which lie closer to the maximums of the curve than barium and krypton or lanthanum and bromine... the same ash but more consistent with the distribution curve of fragments with the same chemical composition... USING THESE EXAMPLES, I CONFIRMED THE CORRECT CHARGE OF THE URANIUM ATOM NUCLEUS equal to 96. Dear sirs! Here are some explanations for my work. A model of the atomic nucleus was developed to explain the adjusted 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 you pack nucleons in a nucleus so that it is droplet and shell-like and with the required number of neutrons? This is how 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 elements between lutetium and hafnium will change slightly. The model was obtained by considering the structures of atomic nuclei from heavy to light. The number of neutrons is approximately equal to the difference between the atomic weight and the number of protons. The number of protons is equal to the atomic number, according to the table.
