Question

What happens to the positrons that are generated in the proton-proton fusion chain?

a) They annihilate with electrons.
b) They escape into space.
c) They form neutrinos.
d) They combine with protons.

Answer 1

Positrons generated in the proton-proton fusion chain escape into space.

Step-by-step explanation:

The positrons generated in the proton-proton fusion chain escape into space. When two hydrogen atoms fuse to form deuterium, positrons are produced along with neutrinos. Positrons are the antimatter version of electrons and have the same mass. They can annihilate with electrons, but in the proton-proton fusion chain, they escape into space.
