sci.nuclear-binding-energy Calculator
Calculates nuclear binding energy per nucleon from atomic mass deficit: BE = (Z×m_H + N×m_n − M_atom)×c². Binding energy per nucleon peaks at iron-56 (≈8.8 MeV/nucleon) — elements above iron release energy by fission; below iron by fusion.
Inputs
Protons Z
Count of items or occurrences.
Neutrons N
Count of items or occurrences.
Results
binding energy (MeV)
Energy holding the nucleus together — the deficit between the mass of the nucleus and the sum of its individual nucleons. Released in fission or fusion.
binding energy per nucleon (MeV/A)
Energy holding the nucleus together — the deficit between the mass of the nucleus and the sum of its individual nucleons. Released in fission or fusion.
mass number A
The computed mass of the object or substance.
SEMF formula
The specific form or variant of the result.
