Who is credited with discovering the concept of radioactivity in 1896 while studying uranium salts?
Answer
Henri Becquerel
Henri Becquerel discovered radioactivity in 1896 during his research on uranium salts. He observed that certain materials emitted radiation naturally without the need for an external power source or electrical equipment. This discovery was a pivotal moment in physics and chemistry, providing a basis for further research into radioactive elements and creating a distinction between materials that emitted radiation naturally and the X-ray technology developed by others.
