GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -Fission occurs when a neutron slams into a larger atom, forcing it to excite and split into two smaller atoms-also known as fission products. Additional neutrons are also released that can initiate a chain reaction. When each atom splits, a tremendous amount of energy is released.

Detailed explanation-3: -Nuclear fission is the formal name for the splitting of an atom. In self-sustained fission, a neutron causes an atomic nucleus to split, and this gives off more neutrons that cause nearby atoms to break apart, giving off yet more neutrons, in a chain reaction (see diagram).
