The binding energy per nucleon measures how tightly a nucleus is held together, peaking at iron-56. Light nuclei release energy by fusing toward that peak — the power source of stars; heavy nuclei release energy by splitting toward it — the basis of fission reactors and bombs. Iron is the ash where both paths end.

Governing equation

\frac{B}{A} = a_{V} - a_{S} A^{- 1/3} - a_{C} \frac{Z ( Z - 1 )}{A ^{4/3}} - a_{A} \frac{( A - 2 Z ) ^{2}}{A ^{2}} + \frac{δ}{A} = 8.72 MeV, A = 56

Reading this result: Iron-56 sits at the very peak — the most tightly bound nucleus, where neither fusion nor fission can extract any more energy.

About this simulation

The full Nuclear Binding Energy tool models a smoke detector with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
