![]() The process by which hydrogen atoms join together in the sun’s core to form helium. Which is a process that occurs in the Sun’s core? An alpha particle (a Helium-4 nucleus) has a total binding energy of roughly 28.3 MeV. You can, but there’s no guarantee it’s going to split nicely in half. But don’t worry there’s plenty more where that came from by most estimates, the sun has enough fuel for about another five billion years. ![]() The sun burns hydrogen - a lot of it, several hundred million tons per second. Hydrogen + hydrogen + hydrogen + hydrogen = helium + energy So every time you fuse 4 hydrogen atoms together to make helium, 26.7 MeV is released. How much energy is released when two hydrogens fuse? It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom. This is what happens to the hydrogen gas in the core of the Sun. What causes hydrogen atoms to fuse together in the Sun’s core?Ī huge amount of mass is above you, squeezing down on you from all sides. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. Nuclear Fusion reactions power the Sun and other stars. What is the process of nuclear fusion in the Sun? This energy can be calculated by the famous Einstein equation, E = mc2. It looks like this in a very simplified way: H + H → He + ENERGY. The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. How does hydrogen combine to form helium?įusion reactions occur when two nuclei come together to form one atom. The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium.
