👤 whose
Whose discovery first identified radioactivity in uranium salts?
Quick Answer
Henri Becquerel’s. In 1896, he found that uranium compounds emit penetrating radiation without needing sunlight.
The Full Story
Henri Becquerel discovered natural radioactivity in 1896 while studying uranium salts and their effect on photographic plates. He originally suspected sunlight might be involved, but later found the radiation occurred on its own. This was the first clear evidence that atoms could spontaneously emit energy. Becquerel’s discovery opened an entirely new field of nuclear science. It was foundational for later work by Marie and Pierre Curie on radioactive elements.
