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...
Radioactive isotopes have unstable nuclei that slowly break apart over time. As they decay, bits of the nucleus (protons and neutrons) are emitted which can cause damage to substances and organisms that are struck by these particles. The simplest type of radiation is the Alpha particle, which is emitted by all elements whose atomic number is 84 or greater. 1. If each alpha particle has the same composition as the nucleus of a Helium atom, how many protons and neutrons...
