Abstract
The Periodic Table Challenge is re-opening. After a successful period during the International Year of the Periodic Table with participants from over 130 countries, IUPAC has decided to make the Periodic Challenge a permanent feature of IUPAC website, linked to information about the Periodic Table.
The challenge has new exciting questions. In order to obtain a certificate one will need to answer 6 out of 10 questions correctly. For schools and classes groups, there is also an opportunity to win a Periodic Table signed by a Nobel Laureate.
