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: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.

Detailed explanation-3: -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-4: -In nuclear fusion, two or more small nuclei combine to form a single larger nucleus, a neutron, and a tremendous amount of energy. Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures.

Detailed explanation-5: -There is a sort of structural quirk which makes an iron nucleus able to fit together with less glue (per nucleon) than any other nucleus. So if you take a heavy nucleus and break it apart, you get extra glue, because the pieces, together, use less glue than what you had in the heavy nucleus.
