  • I can describe the concept of relative atomic mass (don’t mix it up with the average atomic mass)
  • I can calculate the average atomic mass  (don’t mix it up with the relative atomic mass)
  • I can define an isotope as the atom of an element where the nucleus contains a different number of neutrons giving the atom a different atomic mass.
  • I can define a radioactive isotope as an isotope that has an unstable nucleus
  • I can determine the number of valence electrons in an element
  • I can define “nuclear stability” as the cohesion of the nucleus resulting from the fact that an atom has an optimal number of neutrons
