The proton- proton chain converts four hydrogen nuclei into one helium nucleus plus energy.

Question

Quizplus · Accepted Answer

The proton-proton chain is a series of nuclear reactions that occur in the sun to convert hydrogen nuclei (protons) into helium nuclei (alpha particles) and release energy in the form of gamma rays and neutrinos. It involves three main stages, with the fourth stage producing the final helium nucleus. Therefore, four hydrogen nuclei are indeed converted into one helium nucleus in this process.
