Respuesta :
Answer: Both the nuclear reactions releases large amounts of energy.
Explanation: There are two types of nuclear reactions.
- Nuclear fission: In this nuclear reaction, the heavy nucleus splits instantly or on impact of any other particle,releasing some energy.
- Nuclear fusion: In this nuclear reaction, the nucleus of low atomic number fuse or combine together to form a heavier nuclei, releasing some energy.
Option 1: Between these two reactions, only nuclear fusion reactions produce radioactive products. Nuclear fission reactions also produce radioactive products but they are short lived and decay accordingly.
Option 2: Only nuclear fission reactions involve the splitting of atoms, nuclear fusion involves the combining of two atoms.
Option 3: In power plants, nuclear fission reactions takes place predominantly.
Option 4: Both the reactions release large amounts of heat as explained in the definition.
