Bismuth-210 (083210Bi^{210}_{\phantom{0}83}\text{Bi}083210Bi) is a radioactive isotope that decays by emitting beta-minus (β−\beta^-β−) radiation.
Which of the following is the correct decay equation for Bismuth-210?
- A: 083210Bi→084210Po+−1−0e^{210}_{\phantom{0}83}\text{Bi} \rightarrow {}^{210}_{\phantom{0}84}\text{Po} + {}^{\phantom{-}0}_{-1}\text{e}083210Bi→084210Po+−1−0e
- B: 083210Bi→081206Tl+24He^{210}_{\phantom{0}83}\text{Bi} \rightarrow {}^{206}_{\phantom{0}81}\text{Tl} + {}^{4}_{2}\text{He}083210Bi→081206Tl+24He
- C: 083210Bi→082210Pb+−1−0e^{210}_{\phantom{0}83}\text{Bi} \rightarrow {}^{210}_{\phantom{0}82}\text{Pb} + {}^{\phantom{-}0}_{-1}\text{e}083210Bi→082210Pb+−1−0e
Use the graph above to determine the change in mass of the sample of Bismuth-210 between 4 days and 12 days.
Use the graph above to estimate the mass of Bismuth-210 remaining after 18 days.
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.
