Solution

Nuclear Fission Nuclear Fusion
Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one.
Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun.
Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that.
Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is required.
Takes little energy to split two atoms in a fission reaction Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
