Question

the models above illustrate how some elements commonly undergo fusion reactions, while others undergo fission reactions. what is the difference between fusion reactions and fission reactions? explain your answer by discussing the differences in the products atomic mass and energy produced by both reactions.

Explanation:

Fusion combines light - nuclei to form a heavier one with higher atomic mass, releasing vast energy. Fission splits a heavy - nucleus into lighter ones with lower atomic mass, also releasing energy. Fusion releases more energy per reaction than fission under optimal conditions.

Answer:

Fusion reactions combine light atomic nuclei to form a heavier nucleus, increasing atomic mass and releasing a large amount of energy. Fission reactions split a heavy atomic nucleus into two or more lighter nuclei, decreasing atomic mass and releasing energy, but generally less energy per reaction compared to fusion under ideal circumstances.
