Question

In the proton-proton cycle, which is the primary source of energy in the sun, four hydrogen atoms fuse to form a helium atom. What is the approximate net energy released in this reaction?

Professor PC Thomas Classes · Answer

The net effect of the proton-proton cycle is: $4 ^{1}_{1}	ext{H} + 2	ext{e}^- ightarrow ^{4}_{2}	ext{He} + 2
u + 6\gamma + 26.7	ext{ MeV}$.
