The Periodic Table of Chemical Elements is one of the most significant achievements in science, capturing the essence not only of chemistry, but also of physics and biology.
It is a unique tool, enabling scientist to predict the appearance and properties of matter on the Earth and in the rest of the Universe.
2019 will be the 150th anniversary since Dmitry Mendeleev discovered the Periodic System and has been proclaimed the "International Year of the Periodic Table of Chemical Elements" (IYPT2019).
The initiative for IYPT2019 is supported by IUPAC in partnership with the International Union of Pure and Applied Physics (IUPAP), European Association for Chemical and Molecular Science (EuCheMS), the International Council for Science (ICSU), International Astronomical Union (IAU), and the International Union of History and Philosophy of Science and Technology (IUHPS). It was submitted by numerous organizations from over 50 countries around the world.
