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.

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.

To identify a fusion reaction, you can consider two criteria. First, look for an increase in atomic number (Z) and mass number (A) of the nuclei involved compared to the reactants. Second, check if the reaction releases a significant amount of energy, as fusion reactions typically require high energy input and produce substantial energy output.

To identify a fusion reaction, you can look for two key criteria. Firstly, the reactant nuclei should be light elements like hydrogen isotopes (such as deuterium and tritium). Secondly, the product nuclei should be heavier elements with a release of substantial energy, usually in the form of high-energy photons or kinetic energy.
