Chemistry question

Question

Why are radioactive isotopes used for various applications? Select all correct responses.

1. We can detect the radioactivity.
2. We can use the energy given off.
3. They are all artificially produced.
4. They have very short half-lives.
5. They glow in the dark.

Answer 1

The term "various applications" is very general, and so probably all of the answers would be considered correct, even though not all statements are true all the time. For example, some isotopes have very short half lives and are useful for certain applications, but others have very long half lives and are useful for other purposes.
