Answer;
Nuclear fusion
Nuclear fusion reactions convert protons into helium; thus, becoming the source of all energy radiated by the sun.
Explanation;
- Nuclear fusion is a type of nuclear reaction in which two or more nuclei of atoms join to form one or more different atomic nuclei and subatomic particles.
- Nuclear fusion takes place in the sun where protons or hydrogen nuclei collide in a nuclear fusion reaction at very high temperatures to form Helium. This nuclear fusion results in the conversion of 4 hydrogen atoms into helium atom.
