In this video, we look at the atomic number and mass number. First, I discuss how to use the atomic number and the mass number to work out the numbers of protons, neutrons and electrons in atoms of specific elements. We then look at what is meant by isotopes and why these differ in the mass number. Finally, we learn how to work out the structure of ions.
