Element has two or more isotopes that are used to determine its standard atomic weight. The isotopic abundance and atomic weights vary in normal materials, but upper and lower bounds of the standard atomic weight have not been assigned by IUPAC. Element has only one isotope that is used to determine its standard atomic weight. Thus, the.
