U.S. National Committee for IUPAC

The National Academy of Sciences is the U.S. adhering body of the International Union of Pure and Applied Chemistry (IUPAC) and it maintains its relationship with the union through the U.S. National Committee (USNC)/IUPAC. IUPAC serves to advance the worldwide aspects of the chemical sciences and to contribute to the application of chemistry in the service of humankind.

Take the Periodic Table Challenge!
Join people from around the world and test your knowledge of the Periodic Table as we celebrate the International Year of the Periodic Table!

IUPAC100 logoPeriodic Table of Younger Chemists seeking nominations
In celebration of its centenary (IUPAC100) and the International Year of the Periodic Table in 2019, IUPAC and the International Younger Chemists Network (IYCN) have created a Periodic Table of Younger Chemists. Beginning in July 2018, the World Chemistry Congress and IUPAC General Assembly has honored a diverse group of 118 outstanding younger chemists from around the world who in embody the mission and core values of IUPAC. The resulting periodic table highlights the diversity of careers, creativity, and dedication of the young chemists leading us into the next century. Winners are being profiled on the IUPAC100 website and receive a certificate from IUPAC. In July 2018, IUPAC began revealing approximately eight elements each month. The final elements were awarded at the IUPAC General Assembly and World Chemistry Congress in Paris, France in July 2019. For more information, visit

IYPT logo2019 International Year of the Periodic Table
On 20 December 2017, the United Nations (UN) General Assembly proclaimed 2019 to be the International Year of the Periodic Table of Chemical Elements (IYPT 2019). In doing so, the UN has recognized the importance of raising global awareness of how chemistry promotes sustainable development and provides solutions to global challenges in energy, education, agriculture, and health. 
The development of the Periodic Table of the Elements is one of the most significant achievements in science and a uniting scientific concept, with broad implications in Astronomy, Chemistry, Physics, Biology and other natural sciences. The International Year of the Periodic Table of Chemical Elements in 2019 will coincide with the 150th anniversary of the discovery of the Periodic System by Dmitry Mendeleev in 1869, and with the centenary of IUPAC (IUPAC100). More information can be found on the website

International Younger Chemists Network
The International Younger Chemists Network (IYCN) was officially launched at the 49th IUPAC General Assembly in São Paulo, Brazil, in July 2017. The IYCN wants to “create a unified global network of young chemists to communicate, collaborate, educate, and mentor”. To find out more, read more in ChemViews Magazine.(online 5 Dec 2017).

Isotopes MatterIsotopes Matter!!  New Interactive Periodic Table

In partnership with researchers at the King’s Centre for Visualization in Science, a team of IUPAC scientists and educators created an interactive electronic isotopic periodic table. Launched in August 2016, it can be found at The accompanying educational materials inform students and the general public about the many uses of isotopes in our lives. A print version of the periodic table of the isotopes and elements is available at
