HS-PS1-8: Fission, Fusion, and Radioactive Decay

Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during different nuclear processes.

Alpha Decay

Uranium-238 → Thorium-234 + α

Nuclear Fission

U-235 + n → Ba-144 + Kr-89 + 3n

Nuclear Fusion

H-2 + H-3 → He-4 + n

Proton (p⁺)

Neutron (n⁰)
