The periodic table is a fascinating system of order that nature has given the elements. The Russian chemist Dimitri Mendelejew and the German chemist Lothar Meyer recognized this almost simultaneously in 1869, independently of one another. 2019 marks the 150th anniversary of the discovery of the periodic table. The General Assembly of the United Nations and UNESCO have therefore declared 2019 the International Year of the Periodic Table of Chemical Elements, the International Year of the Periodic Table.
