In 2019, ACS is joining in with the United Nations Educational, Scientific, and Cultural Organization (UNESCO) to help celebrate the 150th anniversary of the 1869 publication of Dmitri Mendeleev’s Periodic Table of Chemical Elements. The United Nations International Year of The Periodic Table of Chemical Elements (IYPT 2019) is an opportunity to look both back and forward. We can look back at the remarkable work chemists have done discovering, organizing, understanding, and manipulating elements over the course of chemistry’s comparatively brief history. We can also look ahead to all the discoveries yet to be made – and the ongoing debate about the best way to organize our knowledge about the elements.
ACS will be celebrating IYPT 2019 all year long with research, history, giveaways, events, webinars and more. Check out a list of all our major activities below. Bookmark this page, as new resources will be added throughout the year.
