What did henri becquerel contribute to the atomic theory?

Answer 1

This was not what Henri Bacquerel was famous for. He was a physics lecturer and carried out various experiments. His most famous discovery was by chance leaving some Uranium salts next to a photographic film. This exposed them and turned them white. This led him to realise that some substances gave off nuclear radiation.

Answer 2

Henri Becquerel discovered radioactivity in 1896, which was a significant contribution to the atomic theory by demonstrating that atoms could spontaneously change and emit radiation. This discovery paved the way for further research into the structure of the atom and the development of nuclear physics.

Answer 3

i need somebody smart to answer this, its for my chemistry project!!!!! pleease!

He did not have an atomic model.

Answer 4

Through his experiments dealing with X-rays, he discovered radiation
