Question
Why do light nuclei always participate in nuclear fusion reaction?

Answer

Light nuclei fuse because they have lower binding energy per nucleon; by fusing into a heavier, more stable nucleus, they increase their binding energy and release a massive amount of energy.

Show that the minimum energy needed to separate a proton from a nucleus with $Z$ protons and $N$ neutrons is:
