Nuclear Physics Test - Fission Vs Fusion

In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or smaller, lighter nuclei. Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. Check out the online quiz and learn all about nuclear fusion and fission.
