Mass Defect Calculator
Calculate nuclear mass defect and its energy equivalent
Key Concepts
- Mass defect: "Missing" mass converted to binding energy
- Binding energy: Energy needed to break nucleus apart
- 1 u = 931.5 MeV/c² = 1.66054×10⁻²⁷ kg
- Packing fraction: (M - A) / A
Formulas Used
Mass defect: Δm = Z·m_p + N·m_n - M_actual
Binding energy: E = Δm × c²
m_p = 1.007276 u, m_n = 1.008665 u
