The article considers the periodic table of chemical elements, and that it is a graphic representation of the periodic law (PL), although more than 150 years have passed since the opening of the periodic law, there is no clear formulation of the mathematical formula of this law. The definitions of PL are compared and the work of research scientists is analyzed. Currently, throughout the world, the law is not mentioned in courses in general chemistry and physics, only the table of D.I. Mendeleev is used. This article provides suggestions on how to fill such inconsistencies. Nowadays, there are more than 700 variants of the graphic construction of P.T., the most recognized is IUPAC. The object of our study is the 32-cell version of the periodic table, which, in our opinion, does not break the table into parts with the introduction of lanthanides and actinoids into the lower part of the table. It most fully reflects the similarity of periods and the main physicochemical properties of elements in groups, as well as their periodicity, when joining subscripts (lanthanides and actinides) into a single table corresponding to the natural ordinal number of the location of these elements in periods. The formulas presented in the article are difficult to summarize the P.L., they are difficult to understand, so the goal of our study is to derive a simplified mathematical equation and formulate a periodic law based on an analysis of the literature and its data on periodic changes in the properties of chemical elements and their compounds.
