What is the difference between nuclear fusion and nuclear fission?
In nuclear fusion, small nuclei are combined to form a larger nucleus
– this process releases a very large amount of energy, and is the
main source of energy in the sun. In nuclear fission, large nuclei
break apart to form smaller ones, releasing a large amount of energy.
Fission is used in nuclear power plants to generate energy.
