Our world consists of various elements, which are arranged in the periodic table according to atomic numbers. Russian chemist Dmitri Mendeleev devised the periodic table in 1869. Since then, more than 170 versions of periodic tables have been proposed. In summary, the short form was proposed by Mendeleev, the long form by Werner, the specialty table by Poltar, the planar spiral table and round table by Dammenkov, and the dimensional periodic table represented by Lacey's taper column.
