Nuclear Composition and Size
R = R₀ × A^(1/3)ρ = 2.29 × 10¹⁷ kg/m³Volume = (4/3)πR³Mass-Energy and Binding Energy
E = mc²ΔM = [Z·mₚ + (A-Z)·mₙ] - MEᵦ = ΔM × c² = ΔM × 931 MeVBE per nucleon = Eᵦ/ARadioactivity and Decay
N(t) = N₀e^(-λt)T₁/₂ = 0.693/λ = ln(2)/λA = λN = dN/dtN = N₀/2^nNuclear Reactions
Q = (m_initial - m_final) × c² = (m_initial - m_final) × 931 MeVFor fission: Q ≈ 200 MeV per U-235For fusion: 4¹H → ⁴He + 26.7 MeVGet the complete formula sheet with derivations — continue in Super Tutor
