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 as fusion, and give two different criteria.
To identify a nuclear reaction as fusion, you can consider two criteria. First, if the combined mass of the parent nuclei is less than the mass of the product nuclei, and second, if the reaction involves light atomic nuclei, typically hydrogen isotopes, merging to form heavier nuclei.
