Nuclear fission and fusion reactions give off energy because
A) the binding energy per nucleon is least for nuclei of intermediate size.
B) the binding energy per nucleon is greatest for nuclei of intermediate size.
C) they result in the production of neutrons.
D) they result in the production of plutonium.

Question

Quizplus · Accepted Answer

The binding energy per nucleon is the amount of energy required to break apart a nucleus into its individual protons and neutrons. Nuclei with intermediate mass have the highest binding energy per nucleon, meaning that energy is released when they are formed (fusion) or broken apart (fission).
