The typical materials involved in fission reactions are heavy elements like uranium and plutonium. In contrast, the typical materials involved in fusion reactions are light elements like hydrogen and helium. In a fusion reaction, two or more light nuclei are fused together to form a heavier nucleus, whereas in a fission reaction, a heavy nucleus is split into smaller nuclei. Both fission and fusion reactions release a large amount of energy, but they differ in terms of the amount of energy required to initiate and sustain the reaction, as well as the byproducts produced.
