Question
Why is it impossible to predict when an individual unstable nucleus will decay?
Answer
It is impossible to predict when an individual unstable nucleus will decay because radioactive decay is a random process. Each nucleus has a certain probability of decaying over a given time period, but this does not allow for precise predictions for individual atoms.
Explanation
This question tests the understanding of the random nature of radioactive decay, a key concept in nuclear physics. The answer highlights the inherent unpredictability of decay events, which is fundamental to the study of radioactivity.
Common mistake
Misunderstanding Predictability in Radioactive Decay
Students often believe that the decay of an individual unstable nucleus can be predicted based on its characteristics.
Emphasize that radioactive decay is a random process, and while the half-life can be determined for a large sample, the exact moment an individual nucleus will decay cannot be predicted.
