Radioactivity

Atoms are made up of protons, neutrons and electrons. Change the number of neutrons in an atom and it becomes an isotope, change the number of electrons, it becomes an ion.

This interactive quiz is suitable for GCSE physics students studying structure of the atom, atoms and isotopes and ions.

With the wrong number of neutrons, nuclei can fall apart. A nucleus will regain stability by emitting alpha or beta particles and then 'cool down' by emitting gamma radiation.

This interactive quiz is suitable for GCSE physics students studying stable nuclei, nuclear radiation, half life and nuclear equations.

People are exposed to sources of radiation in all aspects of everyday life. Radioactive sources can be very useful but need handling carefully to ensure safety.

This interactive quiz is suitable for GCSE physics students studying irradiation, contamination, the effects of radiation on the human body and background radiation.

The nuclei of atoms contain a large amount of energy. Releasing this energy would free the world from having to use fossil fuels. There are two methods of doing this: fission and fusion.

This interactive quiz is suitable for GCSE physics students studying nuclear fission, fission reactors and nuclear fusion.

Understanding how to approach exam questions helps boost exam performance. Questions will include multiple choice, descriptions and explanations, using mathematical skills and extended writing.
