Radioactive decay — types?
α, β, γ radiations
Atom — smallest matter unit?
Nucleus and electrons
Rutherford experiment — reveal?
Nucleus with positive charge
Atom — smallest matter unit?
Contains nucleus and electrons.
Goldstein’s experiment — key finding?
Nucleus is dense, positively charged.
Proton number (Z) — role?
