How did ernest rutherford contribute to atom
WebAtoms are the tiny building blocks of all matter. Scientists had known that atoms existed for hundreds of years. But they did not understand what they are made of or how they work. Rutherford proposed his model in 1911. He said that the atom was made up mostly of empty space and that its mass was concentrated in the tiny nucleus. Web15 de dez. de 2024 · Ernest Rutherford postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908. A …

WebIn the now well-known experiment, alpha particles were observed to scatter backwards from a gold foil. Rutherford’s explanation, which he published in May 1911, was that the scattering was caused by a hard, dense core at the center of the atom–the nucleus.
