What was discovered by Antoine Henri Becquerel discover?
When Henri Becquerel investigated the newly discovered X-rays in 1896, it led to studies of how uranium salts are affected by light. By accident, he discovered that uranium salts spontaneously emit a penetrating radiation that can be registered on a photographic plate.
What did Henri Becquerel discover about the atom?
Like Thomson’s discovery of the electron, the discovery of radioactivity in uranium by French physicist Henri Becquerel in 1896 forced scientists to radically change their ideas about atomic structure. Radioactivity demonstrated that the atom was neither indivisible nor immutable.

How did Becquerel accidentally discovered radioactivity?
For some reason, Becquerel decided to develop his photographic plates anyway. To his surprise, the images were strong and clear, proving that the uranium emitted radiation without an external source of energy such as the sun. Becquerel had discovered radioactivity.

What was Antoine-Henri Becquerel studying?
Antoine-Henri Becquerel, a French physicist, was born Dec. 15, 1852. In February of 1896, Becquerel was studying the phosphorescence of various minerals, including some salts of uranium. X-rays had just been discovered the month before, and Becquerel was trying to see if phosphorescent materials produced X-rays.

What was Antoine-Henri Becquerel studying when he discovered radioactivity quizlet?
In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. A device for measuring the radiant flux of electromagnetic radiation.
Who is Antoine-Henri Becquerel and what are his contributions in radioactivity?
Henri Becquerel, in full Antoine-Henri Becquerel, (born December 15, 1852, Paris, France—died August 25, 1908, Le Croisic), French physicist who discovered radioactivity through his investigations of uranium and other substances. In 1903 he shared the Nobel Prize for Physics with Pierre and Marie Curie.
