This lesson will define an isotope and demonstrate how to determine the average atomic mass of an element. It is 8 of 9 in the series titled "Isotopes."

This lesson will introduce isotopes, and explain how they differ from other elements. It will also show that some isotopes are unstable and emit particles and/or radiation. It is 7 of 9 in the series titled "Isotopes."
