Question

what is the net change that occurs during the fusion process in the sun?
two helium nuclei come together to form a larger helium nucleus, two protons, and energy.
four hydrogen nuclei join to form a helium nucleus, two neutrinos, and energy.
six hydrogen nuclei and two electrons join to form a helium nucleus, two protons, two neutrinos, and energy.
two hydrogen nuclei come together to produce a helium nucleus and energy.

Explanation:

In the Sun's fusion process, four hydrogen nuclei (protons) undergo a series of reactions to form a helium - 4 nucleus, along with the release of two neutrinos and energy. This is known as the proton - proton chain reaction.

Answer:

Four hydrogen nuclei join to form a helium nucleus, two neutrinos, and energy.
