In the proton-proton cycle,the eventual product is
A)heavy hydrogen.
B)tritium.
C)helium-3.
D)helium-4.

Question

Quizplus · Accepted Answer

In the proton-proton cycle, four hydrogen nuclei (protons) combine to form a helium-4 nucleus, along with the release of energy in the form of gamma rays and neutrinos. Therefore, the eventual product is helium-4. Choice A (heavy hydrogen) and B (tritium) are not the final products of the proton-proton cycle, while choice C (helium-3) is an intermediate product that can be further fused with another helium-3 nucleus to form helium-4.
