Nuclear fission involves splitting a large nucleus into two smaller ones, while nuclear fusion involves merging two small nuclei into a larger one. Both reactions involve a release of energy, but the inputs and outputs differ:
Energy input:
- Nuclear fission requires the input of a neutron to initiate the reaction and split the nucleus.
- Nuclear fusion requires the input of energy to overcome the electrostatic repulsion of the positively charged nuclei.
Energy output:
- Nuclear fission releases a large amount of energy in the form of heat and radiation, as the split nuclei release excess energy stored in their bonds.
- Nuclear fusion also releases a large amount of energy in the form of heat and radiation, as the merged nuclei release excess energy stored in their bonds.
Overall, both nuclear fission and fusion generate large amounts of energy, but they differ in their inputs and outputs. Nuclear fission relies on the input of a neutron, while nuclear fusion requires the input of energy to initiate the reaction. Both reactions release energy by breaking or forming bonds in atomic nuclei.
