For Release 16 August 2016: IUPAC is releasing Interactive Periodic Table of the Elements

A New Interactive Electronic Version of the IUPAC Periodic Table of the Elements

IUPAC and the King's Centre for Visualization in Science develop innovative educational resources....Isotopes Matter!

Following the global launch on Thursday, August 16, 2016, the new IUPAC interactive 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. 

On August 16, 2016, IUPAC and the King’s Centre for Visualization in Science will release a new interactive electronic periodic table of the elements and isotopes in a special plenary session at the International Conference on Chemistry Education in Kuching, Malaysia.  The interactive periodic table is accompanied by a set of peer reviewed educational resources ( that guide users through the new periodic table and explain the scientific evidence that provides the basis for our understanding of how many isotopes there are for each element, what their relative abundances are, and how atomic weights are determined for each element.  As we recognize that the atomic weights of some elements vary in nature, IUPAC no longer lists these atomic weights with a single value, but rather with an interval. 
These new resources are created for educators and students at secondary and post-secondary levels, and to inform the public about the many uses of isotopes in our lives. They are based on educational practices that encourage engaged and active learning by students.
The new IUPAC interactive electronic periodic table and accompanying educational materials were created by a partnership between an IUPAC Project team of scientists and educators, and researchers at the King’s Centre for Visualization in Science, and build on the work of a previous IUPAC project team to create a print version of the Periodic Table of the Isotopes.  

 “This project responds to requests by educators and students for resources highlighting the importance of isotopes in our lives, and that give students help in using interval atomic weights for elements. brings free engaging and interactive learning resources to the fingertips of students and educators around the world,” says Task Group Co-Chair Peter Mahaffy, Professor of Chemistry at the King’s University in Canada, and co-director of the King’s Centre for Visualization in Science.

About IUPAC: IUPAC was formed in 1919 by chemists from industry and academia. Since then, the Union has succeeded in fostering worldwide communications in the chemical sciences and in uniting academic, industrial and public sector chemistry in a common language. IUPAC is recognized as the world authority on chemical nomenclature, terminology, standardized methods for measurement, atomic weights and many other critically evaluated data. In more recent years, IUPAC has been pro-active in establishing a wide range of conferences and projects designed to promote and stimulate modern developments in chemistry, and also to assist in aspects of chemical education and the public understanding of chemistry.
