Question

what happens during the entire fusion process in the sun? two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released. four hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released. six hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released. eight hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.

Explanation:

In the Sun's fusion process, four hydrogen nuclei combine to form one helium nucleus and two protons, with energy released. This is the proton - proton chain reaction which powers the Sun.

Answer:

Four hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
