International Year of the Periodic Table of Elements


UNESCO proclaimed 2019 as The International Year of the Periodic Table, IYPT2019 to mark 150 years since the publication of this classification by the Russian chemist, Dmitri Mendeleev. Back in 1869, Mendeleev invented the periodic system and the table of elements, an innovative system for classification of known elements based on their physical and chemical properties. The periodic table of chemical elements – still being completed today since the number of known elements continues to increase (the last 4 elements were added in November 2016) – is one of the most significant results of science: it captures the essence not only of chemistry, but also of physics and biology.

The date chosen for the inauguration of the IYPT2019 is 6 March because it was precisely on that day of 1869 that Mendeleev presented the periodic table of elements for the first time to the Russian Chemical Society. This decision by the United Nations aims to recognise the importance of chemistry in promoting sustainable development and in searching for solutions to global challenges in a number of sectors (such as energy, education, agriculture, health) and will provide an opportunity to demonstrate the centrality of chemical elements in connecting cultural, economic and political aspects of the global society through a common language. Moreover, for young people attracted to chemistry and physics, the International Year will represent a stimulus to strive to become future scientists and innovators.
