Quizplus · Accepted Answer

The fundamental nuclear reaction occurring in the core of the Sun is nuclear fusion of hydrogen into helium, also known as the proton-proton chain reaction. This process involves the fusion of four hydrogen nuclei (protons) to form a single helium nucleus, which releases energy in the form of radiation.
