IB Physics SL E.3.7 Decay nuclear changes

IB Physics syllabusFirst assessment 2025
Practise predicting nuclear changes in alpha and beta decay by tracking proton and neutron numbers and linking beta decay to quark change.
How this is tested
- choose alpha, beta-minus, or beta-plus decay from whether a nucleus is neutron-rich or proton-rich
- track alpha and beta-minus steps on a neutron-proton chart to locate the final nuclide correctly
- link beta decay to neutron-proton conversion and state the quark change d -> u when required
