What type of nuclear reaction takes place in the Sun to release energy?
Answer Details
The Sun releases energy through nuclear fusion, a process in which small atomic nuclei are combined to form larger nuclei. In the Sun's core, hydrogen nuclei (protons) fuse together under extreme temperature and pressure to form helium nuclei, releasing enormous amounts of energy in the process.
Nuclear fission is a different process in which large, heavy nuclei (such as uranium-235) are split into smaller fragments. Fission is used in nuclear power stations on Earth but is not the process that powers the Sun. Radioactive decay of helium does not occur - helium is the stable product of the Sun's fusion reactions, not a radioactive source.
