Exam points
- define isotopes as nuclei with the same proton number but different nucleon numbers and distinguish them from other nuclides
- use proton and nucleon-number changes in alpha and beta-minus decay sequences to identify the resulting nucleus or isotope relationship
- explain why precise nuclear-mass measurements provide evidence for isotopes and interpret isotope questions from nuclear data
