150 years ago, Russian chemist Dmitry Mendeleev created the periodic table of elements. In remembrance of this and to emphasize the importance of basic chemical research and the periodic table, the UN declared 2019 the year of the periodic table.

The periodic table reveals the connection between the atomic structure of the chemical elements and their properties. It explains their bonding behavior, reveals the structure of their atomic shell and even allows conclusions about how unidentified elements might be. To this day, the periodic table is the most important guide to chemistry - and there are still plenty of surprises in store.
