An unstable radioactive nucleus, XXX, undergoes a series of radioactive decays. The first decay in this sequence is represented on the grid below:
Identify the type of radiation emitted during this first decay of nucleus XXX to the new nucleus at (84,212)(84, 212)(84,212).
The newly formed nucleus at (84,212)(84, 212)(84,212) subsequently undergoes a decay where its proton number decreases to 828282 and its mass number decreases to 208208208. Write down the type of radiation emitted during this second decay.
Atoms and nuclear radiation Questions
Practise AQA GCSE Physics Atoms and nuclear radiation with exam-style questions for Foundation and Higher tier. 21 questions covering Radioactive decay and nuclear radiation, Nuclear equations, Half-lives and the random nature of radioactive decay, and Radioactive contamination, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
