Key Topics to Revise

1

The Atomic Nucleus - Structure and Properties

  • Nucleus contains protons (positive charge) and neutrons (neutral), collectively called nucleons
  • Atomic number Z = number of protons = number of electrons in neutral atom
  • Mass number A = total number of nucleons = Z + N (where N = number of neutrons)
2

Mass-Energy Equivalence and Binding Energy

  • Unified atomic mass unit: 1u = 1/12 × mass of ¹²C atom = 1.66 × 10⁻²⁷ kg
  • Energy equivalent: 1u = 931.5 MeV
  • Mass defect Δm = [Zmp + (A-Z)mn] - M (actual nuclear mass)
3

Nuclear Forces

  • Nuclear force is fundamental force holding nucleons together
  • Short-range force: acts only up to ~10⁻¹⁵ m (nuclear size)
  • Charge-independent: same force between p-p, p-n, n-n pairs
4

Radioactivity and Nuclear Decay

  • Spontaneous disintegration of unstable nuclei emitting α, β, γ radiations
  • α-decay: ᴬZ X → ᴬ⁻⁴Z₋₂ Y + ⁴₂He (α-particle = He nucleus)
  • β⁻-decay: ᴬZ X → ᴬZ₊₁ Y + ⁰₋₁e + ν̄ (neutron → proton + electron + antineutrino)
