Isotopes and Atomic Mass
Isotopes and Atomic Mass
In this lesson, students will use a simulation of a mass spectrometer. Students will use a slider to adjust the magnetic field to direct either Cl-35 or Cl-37 to the detector.
- Students will run a mass spectrometer simulation to gain an understanding of how the masses and abundances of the isotopes are determined experimentally.
- Students will learn the relationship between the average atomic mass and the masses of the stable isotopes of that element.

This lesson features a simulation of a mass spectrometer. Students will use a slider to adjust the magnetic field to direct either Cl-35 or Cl-37 to the detector.
In doing this activity students will:
- Gain an understanding of how the masses and abundances of the isotopes are determined experimentally.
- Practice doing problems involving isotopic masses and abundances and average atomic mass.
- Learn the relationship between the average atomic mass (as found in the Periodic Table) and the masses of the stable isotopes of that element.
