United Nations elected 2019 a year devoted to the Periodic Table of the Elements, in deference to the original contribution by Dmitri Ivanovich Mendeleev in 1869. Since then, the impact of the Periodic Table in Science has been tremendous, becoming an icon today as the Chemistry Portal, leading to a better acquaintance of the chemical elements. In this article, modern aspects of the Periodic Table of the Elements are presented, complementing an existing historical presentation in this Journal, with special emphasis on the quantum distribution models and on the remarkable role of the elements in Science and Nanotechnology.
