Question

summarize the history of radioactivity by choosing the scientist(s) involved with each discovery. conducted experiments with uranium - containing minerals and pure uranium. came up with the term
adioactivity.\ showed that uranium in a mineral gave off radiation even without being exposed to the sun. discovered radium and polonium. conducted experiments with fluorescent minerals and photographic plates.

Explanation:

• Henri Becquerel conducted experiments with uranium - containing minerals and pure uranium and also conducted experiments with fluorescent minerals and photographic plates. He showed that uranium in a mineral gave off radiation even without being exposed to the Sun.
• Marie and Pierre Curie discovered radium and polonium.
• Marie Curie came up with the term "radioactivity".
