The periodic table was first designed by the Russian scientist Dmitri Ivanovich Mendeleev. The announcement by the United Nations will help to raise the profile of how chemistry can provide solutions to global challenges in agriculture, education, energy and health. This year marks the 150th anniversary of the first publication of the periodic table by Mendeleev. |
