On the occasion of the International Year of the Periodic Table of Chemical Elements, this article reviews the evolution of the first version of Mendeleev’s modern table from 1869 to the present day. After a brief introduction, the achievements of the Russian chemist are considered, his periodic law based on the increasing order of the atomic weight of the chemical elements, their successes and setbacks. The change of paradigm and the periodic law of Moseley settled in the increase of the atomic number and the further development and new contributions to the periodic table until our days are also tackled.
