The year 2019 marked the 100th anniversary of IUPAC and also the 150th anniversary of the development of the Periodic Law of the Elements. To celebrate these anniversaries, IUPAC is hosting an online, global challenge about the Periodic Table of the Elements. Thousands of players from 136 countries had participated in the online challenge aimed at a global audience of young students, encouraging them to become part of a global community that is excited about chemistry.

When contestants successfully completed the Periodic Table Challenge with at least 60 % grade, they could advance to the Nobelium Contest for a chance to win a limited edition Periodic Table autographed by a Nobel Laureate in Chemistry! In the Nobelium Contest, participants were invited to share their passion and creativity about chemistry by highlighting the role of the Periodic Table in a creative manner. The entries could be focused on science, art, or education and outreach.

All entries are shared online and up for vote for People’s Choice and also judged by the IUPAC panel of experts based on three broad categories: creativity, commitment, and impact.

The Spring winners were announced on 1 April 2019, the summer winners were announced in sync with the actual 100th anniversary of IUPAC (28 July 2019), the fall winners of the Nobelium Contest were announced in November 2019 and the final Winter winners are:
