IUPAC IUPAC's New Periodic Table Challenge!
Dear National Adhering Organizations,
I wanted to share the news about the new PTChallenge which we launched on Tuesday. In 2 days we had 78 Countries, 4000 pins and 6000 tests taken. You can see and play at the link below. If your country is missing, we would certainly appreciate you and/or your colleagues give it a try! Follow us on Twitter @iupac, #PeriodicTableChallenge
PT Challenge merchandise is available on the IUPAC Shop https://iupac.org/shop/
