![]() ![]() ![]() 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. 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.Īn element-by-element review accompanies the IPTEI and includes a chart of all known stable and radioactive isotopes for each element. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java. 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. Take a look at the periodic table, color coded to roughly show the metals and other elements. The IPTEI is modeled on the familiar Periodic Table of the Chemical Elements. The elements that are not metals are called nonmetals. 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.The background color of the element lets you know if it is: Metal, Alkaline Metal, Alkaline Earth Metal, Transition Metal, Lanthanide, Actinide. This chart uses the following classifications for color coding. The key is located in the center of the top of the page.
