Henri Becquerel accidently discovered radioactivity while conducting experiments on phosphorescence. He saw that photographic plates that were still wrapped in their black paper packaging was exposed when placed near uranium salts. Therefore, this suggested a type of radiation that can pass through solid matter. He went on the share a Nobel prize with the Curies.

What are becquerel rays?
"Becquerel rays" is an earlier term for what is now known as radioactivity. They are the emissions of energy and particles from the decay of unstable atomic nuclei, discovered by Henri Becquerel in 1896. These rays can be harmful to living organisms and have important applications in medicine, industry, and research.
How did frank Henry fleer invent gum?
Frank Henry Fleer did not invent gum; however, he is known for developing the first commercially successful bubble gum called "Blibber-Blubber" in 1906. Fleer experimented with different formulas until he created a batch that could stretch without breaking and hold its flavor. This innovation laid the foundation for the modern bubble gum we know today.
How was becquerel convinced at first that his hypothesis was supported?
Henri Becquerel was convinced that his hypothesis about the spontaneous emission of radiation from uranium was supported when he observed that uranium chloride crystals exposed to sunlight could fog a photographic plate wrapped in opaque paper. This suggested that something unseen was being emitted by the uranium that could cause this effect.
How was becquerel convinced atfirst thathis hypothesis was supported?
Becquerel was convinced that his hypothesis was supported when he observed that photographic plates wrapped in opaque material were still fogged after being exposed to uranium salts. This suggested that an invisible form of radiation was being emitted from the uranium, supporting his hypothesis that certain materials could emit energy without external stimulation.
What scientists were involved in the discovery of radioactivity?
Marie Curie, Pierre Curie, and Henri Becquerel were key scientists involved in the discovery of radioactivity in the late 19th and early 20th centuries. Marie Curie's work with radioactive materials led to her pioneering research on radioactivity for which she was awarded Nobel Prizes in Physics and Chemistry.
