Enter mass number and atomic mass to get binding energy per nucleon from the mass-energy relation, indicating nuclear stability. Runs entirely in the browser.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Binding energy per nucleon | B/A = total binding / A | Nuclear physics texts |
| Peak value | ≈8.79 MeV at Fe-56 | AME2020 |
| Fission vs fusion | Both move toward the peak | Nuclear energy principles |
| Energy units | 1 MeV = 1.602×10⁻¹³ J | CODATA 2018 |
| Mass data source | Atomic Mass Evaluation | AME2020 |
| Stability | Higher B/A = more stable | Stability systematics |
