Nuclear equations describe the nuclei that are involved before and after the reaction. In one to two short short and small sentences, explain how you would identify the reaction as fusion, and give two different criteria. Make sure your answer makes sense and is human written

Answer 1

In a fusion reaction, lighter nuclei combine to form a heavier nucleus, often releasing a significant amount of energy. Two criteria to identify fusion are: 1) the initial reactants typically consist of isotopes of light elements, like hydrogen, and 2) the resulting product has a greater atomic mass than either of the original nuclei.
