Color-coded pie charts in each element cell display the stable isotopes and the relatively long-lived radioactive isotopes having characteristic terrestrial isotopic compositions that determine the standard atomic weight of each element. The IPTEI is intended to hang on the walls of chemistry laboratories and classrooms.Įach cell of the IPTEI provides the chemical name, symbol, atomic number, and standard atomic weight of an element. The IPTEI is modeled on the familiar Periodic Table of the Chemical Elements. eTOC Alert ‘Pure and Applied Chemistry’ – November 2023 Ībstract: The IUPAC Periodic Table of the Elements and Isotopes (IPTEI) was created to familiarize students, teachers, and non-professionals with the existence and importance of isotopes of the chemical elements.eTOC Alert ‘Pure and Applied Chemistry’ – December 2023.Green Chemistry for Life grants presented to Top Young Scientists.Teaching ethics and core values in chemistry education – Call for papers.IUPAC Green Book – New Abridged Version.Nominations Open for the 9th Polymer International-IUPAC Award.
