Question
What is radioactive decay?
Answer
Radioactive decay is the process in which an unstable nucleus emits radiation in order to reach a more stable state.
Explanation
This answer is strong because it clearly defines radioactive decay and emphasizes the role of instability in the nucleus. The question tests the student's understanding of the fundamental concept of radioactive decay.
Common mistake
Misunderstanding Radioactive Decay
Students often confuse radioactive decay with a predictable process, thinking they can determine when an unstable nucleus will decay.
Emphasize that radioactive decay is a random process, and it is impossible to predict the exact moment an individual unstable nucleus will decay.
