\(B = Zm(^{1}\textrm{H}) + Nm_n - m_a\), where \(Z\) is the proton number of the atom, \(m(^{1}\textrm{H})\) is atomic mass of \(^{1}\textrm{H}\), \(N\) is the neutron number, \(m_n\) is the rest mass of the neutron, and \(m_a\) is the rest mass of the atom.

The "Mass Defect", also termed mass deficit, or mass packing fraction, describes mass change (decrease) in bound systems, particularly atomic nuclei.
