What is Nuclear reaction ?

Nuclear reaction, change in the identity or characteristics of an atomic nucleus, induced by bombarding it with an energetic particle.

The bombarding particle may be an alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion.

Nuclear Fusion reactions power the Sun and other stars.

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.
