The year 2019 marks 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. With thousands of players from more than 100 countries have already participated in this activity, this online challenge is aimed at a global audience of young students, encouraging them to become part of a global community that is excited about chemistry.

When a contestant completes the Periodic Table Challenge with at least 60 % grade, they can 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 are invited to share their passion and creativity about chemistry by highlighting the role of the Periodic Table in a creative manner and in one of the following categories: Science, Art, or Education.

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. Winners of the Nobelium contest will be announced throughout the year in four stages (spring, summer, fall, and winter).

The Spring winners of the Nobelium Contest were announced at the ACS meeting in Orlando, Florida (USA) in April 1st, 2019 AND THE WINNERS ARE:

Rita Godoroja, chemistry teacher from Moldova, for Periodic Table and Personal Values, a table where personal values are passionately associated with the chemical elements

Thierry Brassac, University of Montpellier, France, for Atome Hôtel, a web textbook/documentary for science dissemination dedicated to the world of atoms

Antonio Palumbo Piccionello and Antonella Maggio, University of Palermo, Italy, for Mendel’s Pea-riodic Table, a creative table emphasizing that scientists can fight the scientific illiteracy with irony and humor

Jose Francisco Cota, high school student from Mexico, for Periodic Mendeleev, a creative portrait of Dmitri Mendeleev

Giulia Mason, student at the University of Padova, Italy, for Lady Neon of the House of Neon and her creativity and passion in representing the noble gas neon

Mitchell Harvey, University student from USA, for his High School Periodic Table Display and commitment in creating the display case at the North Little Rock High School



In addition to the Nobelium Winners, three entries were recognized for their popularity:

Georgiana Stoica, biochemist from Spain, for her Ode to nihonium

Ilknur Koyuer, high school chemistry teacher from Turkey, for his Hand-in-hand with elements

Makan Wang, 6yo aspiring scientist from Australia, for his Periodic Table Song
