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: -Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures. That’s because a great deal of energy is needed to overcome the force of repulsion between the positively charged nuclei.
Detailed explanation-3: -It takes such a great deal of energy to produce nuclear fusion that in our modern and mature universe, nuclear fusion will only occur naturally inside stars like our sun, where the heat and pressure are sufficient to press light atomic nuclei together to form heavier elements.
Detailed explanation-4: -Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun. Byproducts of the reaction: Fission produces many highly radioactive particles.
Detailed explanation-5: -The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium.
