Working with an international team of scientists from Australia, Canada, France, Japan, Singapore, and the United States, Sara Glidewell used Adobe Illustrator to create a Periodic Table of Elements and Isotopes in 2016. She created the IUPAC Periodic Table of Elements and Isotopes for this international team that appears as Figure 1 in the publication “IUPAC Periodic Table of the Elements and Isotopes (IPTEI) for the Education Community (IUPAC Technical Report)” by N. E. Holden et al., which was published in Pure and Applied Chemistry, 90(12), 1833–2092 (2018) and is an authoritative resource for the educational community. See https://doi.org/10.1515/pac-2015-0703.
The International Union of Pure and Applied Chemistry (IUPAC) website (https://iupac.org/iptei/) summarizes the importance of this Periodic Table stating:
“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. The IPTEI is modeled on the familiar Periodic Table of the Chemical Elements. The IPTEI is intended to hang on the walls of chemistry laboratories and classrooms. "
“Each cell of the IPTEI provides the chemical name, symbol, atomic number, and standard atomic weight of an element. 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 background color scheme of cells categorizes the 118 elements into four groups: (1) white indicates the element has no standard atomic weight, (2) blue indicates the element has only one isotope that is used to determine its standard atomic weight, which is given as a single value with an uncertainty, (3) yellow indicates the element has two or more isotopes that are used to determine its standard atomic weight, which is given as a single value with an uncertainty, and (4) pink indicates the element has a well-documented variation in its atomic weight, and the standard atomic weight is expressed as an interval.
“An element-by-element review accompanies the IPTEI and includes a chart of all known stable and radioactive isotopes for each element. Practical applications of isotopic measurements and technologies are included for the following fields: forensic science, geochronology, Earth-system sciences, environmental science, and human health sciences, including medical diagnosis and treatment.”
Recognizing that there would be substantial educational value to translating Figure 1 to other languages so that it could hang on walls of science classrooms and laboratories, Dr. N. E. Holden (National Nuclear Data Center, Brookhaven National Laboratory, Upton, NY, retiree) worked with Randy Coplen, having extensive experience in printing, and Sara Glidewell came together to create the educational product, the International Periodic Table of Elements and Isotopes, whose headquarters is in Seahurst, Washington.
