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.

2019 Declared International Year of the Periodic  Table
On 20 December 2017, the United Nations (UN) General Assembly proclaimed 2019 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). The events of IUPAC100 and of IYPT will enhance the understanding and appreciation of the Periodic Table and chemistry in general among the public. The 100th Anniversary of IUPAC will be on the UNESCO Calendar of Anniversaries on 28th July 2019.

46th World Chemistry Congress, Brazil, July 2017
The 46th World Chemistry Congress was held in São Paulo, Brazil, July 9-14, 2017. The 49th IUPAC General Assembly overlapped with the congress, which took place July 7-13. For more information, visit the Congress website.2017 congress logo

To introduce younger chemists to the activities and projects of the International Union, IUPAC holds a Young Observer program. Every two years, younger chemists from around the world attend IUPAC division and committee meetings of the General Assembly to learn more about the union. Many of them ultimately become involved in the union in various ways. This year, seven U.S. IUPAC Young Observers participated in the General Assembly and shared their experiences on the American Chemical Society's Axial blog: They are:

  • Jens Breffke, Boston Electronics Corp.
  • Raychelle Burks, St. Edward's University, Austin, Texas
  • John Matson, Virginia Tech
  • Brandon Presley, NMS Labs, Willow Grove, Pennsylvania
  • Dean Tantillo, University of California, Davis
  • Javier Vela, Iowa State University
  • Yu (Frank) Yang, University of Nevada, Reno

IUPAC Announces the Names of the Elements 113, 115, 117, and 118
On 28 November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), respectively for element 113, 115, 117, and 118. For more information, see

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 has created new IUPAC interactive electronic periodic table. The accompanying educational materials inform students and the general public about the many uses of isotopes in our lives. Following the global launch on August 17, 2016, the new IUPAC interactive electronic periodic table and accompanying resources can be accessed at A print version of the periodic table of the isotopes and elements is available at Further details will be published in the peer-reviewed IUPAC Journal, Pure and Applied Chemistry.
