Q1 · Nuclei and Radioactivity · MEDIUM
A radioactive nucleus undergoes a series of decays: it first emits an alpha particle, then a beta particle, and finally another alpha particle. If the original atomic number was Z and mass number was A, what are the atomic number and mass number of the final nucleus?
Q2 · Nuclei and Radioactivity · EASY
A radioactive nucleus has a half-life of 10 days. What fraction of the original sample will decay in 30 days?
