#P5.3.1
recall that some nuclei are unstable and may split into two nuclei and that this is called nuclear fission
#P5.3.2
relate the energy released during nuclear fission to the emission of ionising radiation and the kinetic energy of the resulting particles
#P5.3.3
explain how nuclear fission can lead to further fission events in a chain reaction
#P5.3.4
describe the process of nuclear fusion and recall that in this process some of the mass may be converted into the energy of radiation
