Embed an image that will launch the simulation when clicked Click to Run Use this HTML code to display a screenshot with the words 'Click to Run'. • Isotopes • Atomic Mass. Topics • Isotopes • Atomic Mass Description Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element. Sample Learning Goals • Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons.

• Given information about an element, find the mass and name of an isotope. • Give evidence to support or dispute: “In nature, the chance of finding one isotope of an element is the same for all isotopes.” • Find the average atomic mass of an element given the abundance and mass of its isotopes. • Predict how the mass and name of an isotope will change given a change in the number of protons, neutrons or electrons. • Predict how the average atomic mass of an element changes given a change in the abundance of its isotopes. Version 3.02.

The NIST Isotope Enrichment Calculator is a program written in Visual Basic which determines the percentage of 15N enrichment of stable isotope-labeled peptides or proteins. A multinomial analysis of Hsu (Anal. 560 1356-1361 (1984)) is used to determine the theoretical isotopic distribution of an input sequence at incremental isotopic percentages which are compared with an input experimentally derived profile. The theoretical profile of 15N percentage which maximizes the Pearson correlation as described by MacCoss et al. (Anal. 77 7646-7653 (2005)) is output along with the coefficient. This software was developed at the National Institute of Standards and Technology by employees of the Federal Government in the course of their official duties.
