Nuclear reactions can be written out in equation form with information about the nuclei that take place in the fusion reaction and the nuclei that are produced. In one to two sentences, explain how you would identify the reaction fusion, and give two different criteria.

Answer 1

To identify a fusion reaction, one can look for the presence of light nuclei as reactants, such as hydrogen or helium isotopes, and heavier nuclei as products. Another criterion could be the release of a significant amount of energy, indicating a high-energy reaction.
