Common mistake
Misunderstanding Radioactive Decay
Students often think that radioactive decay is a predictable process, believing they can determine exactly when a specific nucleus will decay.
Emphasize that radioactive decay is a random process, and while the half-life can be estimated for a large sample, the exact moment of decay for an individual nucleus cannot be predicted.
