Sub-knowledge points
Alpha decay is a quantum tunneling processIt is governed by the strong nuclear force and Coulomb repulsionAlpha decay energy is related to the mass difference between parent and daughter nuclei
Higher-order knowledge points
Nuclear shell modelLiquid drop modelFission theory
Main parameters and performance indicators
Alpha particle: Helium-4 nucleus (2 protons, 2 neutrons)Parent nucleus: The unstable heavy nucleus undergoing decayDaughter nucleus: The resulting nucleus after emission
