5.2.3 — Radioactive decay

Core

• 5.2.3.1 — Know radioactive decay is a spontaneous random change in an unstable nucleus that may emit α, β, and/or γ radiation
• 5.2.3.2 — State that α- or β-decay changes the nucleus into that of a different element

Supplement

• 5.2.3.3 — Know isotopes may be radioactive due to excess neutrons or because nuclei are too heavy
• 5.2.3.4 — Describe effects of α, β, and γ emissions on nucleus including increased stability and reduction in excess neutrons
• 5.2.3.5 — Use decay equations in nuclide notation to show α, β and γ emissions
