GENERAL KNOWLEDGE

Detailed explanation-1: -In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Detailed explanation-2: -In nuclear fission, we split large unstable atoms into smaller, more stable ones and release binding energy. In nuclear fusion, we join small unstable atoms into larger, more stable atoms, and also release binding energy.

Detailed explanation-3: -Nuclear fusion is the joining of two nuclei to form a heavier nuclei. The reaction is followed either by a release or absorption of energy. Fusion of nuclei with lower mass than iron releases energy while fusion of nuclei heavier than iron generally absorbs energy.

Detailed explanation-4: -In nuclear fission, atoms are split apart, which releases energy. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation.

Detailed explanation-5: -Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
