IUPAC Periodic Table Challenge: Nobelium Contest

IUPAC Periodic Table Challenge: Nobelium Contest. DOI:

After a first round based on the knowledge of the participant of the chemical elements, in this new phase of the Challenge, participants were invited to share their passion and creativity about chemistry. The entries were supposed to highlight the role of the Periodic Table in a creative manner. We received a variety of submissions including videos, poems, songs, and paintings. Entries were categorized into science, art, and outreach or community activities related to the science education and the Periodic Table. We were genuinely surprised and inspired by the dozens of pieces of art that we were receiving from all around the world. A jury as well as popular votes casted for each entry decided who were to receive the special limited edition IUPAC Periodic Tables signed by the Nobel laureates. That was one of the most difficult tasks of this activity, as the quality, originality, and diversity of the entries were truly amazing.

The artist is Swaprabha Chattopadhyay, a high school student from India.
