Detailed explanation-1: -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.
Detailed explanation-2: -In the Sun, the nuclear reaction which occurs is called the proton-proton cycle, in which four Hydrogen atoms are combined in a series of reactions to form one Helium atom; this chain of reactions also produces energy (in the form of gamma rays) and some other particles called neutrinos.
Detailed explanation-3: -nuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amounts of energy are released.
