Isotopes and Relative Atomic Mass (Sec 4 SE and Sec 4 EST)

In this brief video, students review the concepts of isotopes and relative atomic mass. In the Desmos Activity below, students practice the naming convention for isotopes as well as calculating relative atomic mass. Answers are included so that they can check their work.

Learning Goals:

To define isotopes as atoms of the same element whose nuclei have different numbers of neutrons and therefore different atomic masses
To explain qualitatively the concept of relative atomic mass
