Nuclear Chemistry Fusion and Fission

Nuclear Chemistry Fusion and Fission. Nuclear Fission. The splitting of a nucleus into smaller fragments is called nuclear fission. Heavy atoms (mass number>60) tend to break into smaller atoms, thereby increasing their stability . Nuclear fission releases a large amount of energy .
