What does the element curium smell like?

Answer 1

No one has ever cataloged a likely smell. All of the curium available on Earth has been synthesized by nuclear colliders, although some isotopes have very long half-lives.

For a person to smell it, there would have to be more than microscopic amounts, and since it tends to bio-accumulate, there would be a serious risk of getting bone cancer from its radiation.

Answer 2

Curium is a radioactive element and does not have a smell because it is not in the form of a compound that can interact with our olfactory receptors. Handling curium is extremely dangerous due to its radioactivity, and it should only be done by trained professionals in controlled laboratory settings.
