Question on: JAMB Physics - 2001

The sun produces energy through nuclear fusion. * **Nuclear fusion:** This process involves the combination of lighter atomic nuclei, such as hydrogen, to form a heavier nucleus, such as helium. This process releases a tremendous amount of energy. * **Nuclear fission:** This involves the splitting of a heavy nucleus into lighter nuclei, also releasing energy but is not the primary energy source of the sun. * **Electron collision:** While electrons are involved in various atomic processes, electron collisions are not the primary energy-producing mechanism in the sun. * **Radioactive decay:** Radioactive decay is the process by which an unstable nucleus loses energy, but it is not the primary source of energy generation in the sun.
