The binding energy per nucleon is lower for a very heavy nucleus than for iron-56. What is the main reason?
Neutrons repel one another strongly in a large nucleus
The electrons of a heavy atom pull on the protons
A heavy nucleus has fewer nucleons at its surface than iron
Every proton repels every other proton, and this long-range repulsion grows faster than the attraction of near neighbours

← A nucleus with 190 nucleons breaks in two equal fragments. Before the break its binding energy per nucleon is 7.5 MeV, and each fragment has 8.4 MeV per nucleon. Find the total energy given out.
A heavy nucleus with 224 nucleons and 7.65 MeV per nucleon splits into two unequal nuclei. One has 96 nucleons with 8.55 MeV per nucleon, and the other has 128 nucleons with 8.45 MeV per nucleon. How much energy is released? →
