Isotopes Matter

What are isotopes, and why do I need to know about them?

These resources will explore these questions and more, including how the new atomic weight intervals came to be, and how to use them. Here you will explore the interactive, electronic version of the IUPAC Periodic Table of the Elements and Isotopes, and discover some of the many ways in which knowledge of isotopes matters. These peer-reviewed resources have been developed as part of an IUPAC project to increase understanding of isotope science, as well as some of the many applications of this field of study.
