ALTERNATIVE MODEL OF CALCULATIONS OF VALUES OF ATOMIC RADIUS
DescriptionThe article presents the results of the development of an alternative model for calculating the values of atomic radius. A formula was derived for calculating the atomic radius of the elements of the Periodic System of DI Mendeleev. The optimal calculation conditions for the proposed model are found. It is shown that the curve of the dependence of the value of the correction coefficient x on the atomic number of the element in form coincides with the dependence of the ionization energy on the charge number

Description
Studying natural phenomena in all their diversity, humanity worked experienced in every field of science the model of perceiving the world and methods of obtaining information. The development of science currently cannot be imagined without research on the intersection of its regions. This article presents the results of the automated systemcognitive analysis of the size of atoms from the main characteristics that are of research at the interface of General chemistry elements and intelligent systems. Dependence of nuclear radius, mass and of the atom and the charge number are identical in shape and size, which is probably connected with the linear increase of these parameters in the Periodic system of chemical elements. There is also a similar form of the dependences of radii of atoms from the factors ex and x, because these factors are interrelated. The obtained results of the ask analysis have confirmed the theoretical assumptions and the formulae of the dependence of main characteristics of the atom

INTERRELATION OF THE MODEL OF CALCULATIONS OF ATOMIC RADIUS AND VARIOUS SYSTEM CHARACTERISTICS
DescriptionIn this article, we discuss the relationship between the previously obtained model for calculating atomic radii with electrodynamics, the hydrodynamic model of the planets of the Solar System, and the Rfunction of the structural organization of electronic systems. It is shown that the curve of the dependence of the value of the correction coefficient e x on the atomic number of the element in form coincides with the dependence of the ionization energy on the mass of the atom and the Rfunction on the nuclear charge. The concept of the "atomic nucleus potential", which takes into account the energy of the nucleus and the charge of the nucleus of the atom, is introduced. It is shown that the radius of an atom is the product of the nuclear potential by a factor kx , taking into account the characteristics of electronic levels; the energy of the nuclear reaction is the work of the forces of the field (potential) of the atomic nucleus along the displacement of the atomic charge. The dependence of the potential of the nucleus on the charge number in the Mendeleev’s Periodic Table is shown. It is shown that any system of satellites (or atomic shells) has a constant ratio of its Kepler number to the mass of the central body around which they rotate. It is shown that in the Table of Mendeleev's chemical elements and in the solar system, the fundamental value is the mass of the center (the nucleus of the atom or the center of the orbit). The ratio of the Kepler number to the mass of the central body is a constant, within the accuracy of construction and calculations

Description
The article presents the results of studies of changes in the atomic radii of isotopes of the elements of the periodic table. With using the massradial model of calculations, the values of atomic radii for isotopes of chemical elements were obtained. It is shown that the atomic radius of different isotopes of one element is different and depends on the mass and radius of the nucleus. To study the changes in ∆Rav values in the groups and periods of the Periodic Table of Chemical Elements, the ∆Rav dependences on the period number and group number are constructed. It is found that the values depending on the number ∆Rav period / group for the delements lie in the low ∆Rav values for selements  in high ∆Rav values, and pelements  in average values ∆Rav. It is shown that when the atomic nucleus is increased by 1 neutron, the atomic radius increases from 0.01 to 4.76 pm, which is due to the physical effect inside the atom

DEVELOPMENT OF A NEW MODEL OF CALCULATIONS OF VALUES OF ATOMIC RADIUMS
DescriptionThe article presents the results of studies of changes in the atomic radii of the elements of the periodic table, depending on their atomic masses. It is shown that the appearance of p and dorbitals introduces a significant contribution to the value of the atomic radius, and the appearance of forbitals makes a significantly smaller contribution to the given value. A radialmass model of calculations of atomic radii for the elements of the Periodic Table was developed. Optimal conditions for making calculations were chosen. For the first time the values of atomic radii for elements with the order number 103120 are calculated. It is shown that the values of atomic radii for elements with the order number 103120 are in the range from 140 to 335 picometers and regularly change in the period

KEPLER'S NUMBERS IN THE MODEL OF THE RUTHERFORDBOHR
DescriptionThe change in the Kepler’s atomic number in the Periodic Table of Mendeleev is studied. It is shown that its values decrease regularly with increasing nuclear charge. An alternative formula for computing the values of the Kepler’s atomic number is proposed. It is shown that the ratio of the atomic number of Kepler’s to the mass of the atom is a constant for each period. The values of these constants are calculated
