Russian chemist Dmitri Mendeleev published his first draft of chemistry's Periodic Table of Elements in 1869. It had only 63 elements on it. As of 2019, the Periodic Table has 118 elements on it. IYPT 2019 logo The United Nations has declared 2019 the International Year of the Periodic Table of Chemical Elements, to commemorate the 150th anniversary of Mendeleev's publication. Activities all around the world are part of this commemoration. Among the activities:

  • The International Union of Pure and Applied Chemistry (IUPAC) has launched an online quiz, the Periodic Table Challenge. The challenge has two rounds, a quiz and an artistic competition; prizes include a Periodic Table signed by a Nobel laureate.
  • The University of Waterloo in Ontario, Canada, is having a Mendeleev Mosaic competition, for which participants create an art work showing or inspired by Mendeleev.
  • The Royal Australian Chemical Institute has issued a call for Stories from the Periodic Table, submissions from people who have had a personal connection with the Periodic Table or an element in particular.
  • A group in Michigan has set a goal of making the world's largest Periodic Table, with each element measuring 216 inches across and 162 inches up and down.
  • A group in France is planning much the same thing, to adorn the side of a building in Paris.
  • Various annual chemistry events around the world will this year have a special focus on the Periodic Table.

A special ceremony in Tokyo in December will mark the official closing of the year of celebration.
