The BasicsEdit

  • You will be required to define the meaning of isotopes along the lines of "atoms containing the same number of protons and electrons but differing numbers of neutrons."
  • You would be required to know that isotopes behave in the same manner chemically but have different masses.
  • You should also know that some isotopes are stable but that others are radioactive.
  • You should also be able to work out the Relative Atomic Mass of an element given the abundances of its isotopes - see Mass Number for an example of this calculation.
