Detailed explanation-1: -Fusion reactions occur when two nuclei come together to form one atom. The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. It looks like this in a very simplified way: H + H → He + ENERGY. This energy can be calculated by the famous Einstein equation, E = mc2.
Detailed explanation-2: -The Sun is a main-sequence star, and thus releases its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.
Detailed explanation-3: -Two helium-3 nuclei fuse together, producing helium-4, two protons (hydrogen-1), and energy, Helium-3 fuses with helium-4, producing beryllium-7, which decays and then fuses with another proton (hydrogen-1) to yield two helium-4 nuclei plus energy.
Detailed explanation-4: -In the basic hydrogen fusion cycle four hydrogen nuclei (photons) come together to make a helium nucleus. This fusion cycle releases energy in the core of the star i.e., energy is liberated in this process.
