Question

Quizplus · Accepted Answer

Iron has the most tightly bound nucleons due to its balanced combination of strong nuclear force and electrostatic repulsion between protons. This makes it the most stable nucleus, and any further fusion or fission of iron requires energy instead of releasing it. This property of iron makes it important in the formation of stars and the production of energy in nuclear reactors.
