Activity 27-7. Nuclear decays II [Accompanies Section 27-6] (a) Rank the following decays in order of the change in atomic number Z that occurs in the decaying nucleus, from most positive (greatest increase in Z) to most negative (greatest decrease in Z). If any two decays cause the same change in Z, state this. Explain how you made your ranking. (i) Alpha decay (emission of a He nucleus of charge +2e) (ii) Beta-minus decay (emission of an electron of charge...
