Periodic law

"The properties of ordinary bodies, as well as the forms and properties of the compounds of the elements, and therefore the properties of simple and complex bodies they form, are periodically dependent on their atomic weight, ”the creator Dmitry Ivanovich Mendeleev formulated the periodic law. Thus, he took another step towards overcoming the chaos of the world system, and modern chemists and physicists continue his struggle. Gafni, whose existence suggested Mendeleev back in 1869, was opened in 1923, after the death of a chemist. In 2016, almost 150 years after the revolutionary opening, four more short -lived elements were received by the unique names synthesized artificially, but organically inscribed in the periodical table.
