Radioactive decay results in the emission of α\alphaα-particles, β\betaβ-particles, and γ\gammaγ-radiation.
Which type(s) of emission result in a change in the nucleon number (mass number) of the decaying nucleus?
α\alphaα-particle emission only
β\betaβ-particle emission only
α\alphaα-particle and β\betaβ-particle emission
β\betaβ-particle and γ\gammaγ-radiation emission
