WebThe electrons in the atom must be orbiting around this central core, like planets around the sun, Rutherford proposed. Rutherford carried out a fairly simple calculation to find the size of the nucleus, and found it to be only about 1/100,000 the size of the atom. The atom was mostly empty space. WebNov 19, 2024 · Another significant contribution to atomic theory was made in 1827 by botanist Robert Brown, who noticed that dust particles floating in water seemed to move randomly for no known reason. In 1905, Albert Einstein postulated that Brownian motion was due to the movement of water molecules. ... Ernest Rutherford, one of Thomson's …
WebJan 30, 2024 · In 1909, Ernest Rutherford (1871-1937) performed a series of experiments studying the inner structure of atoms using alpha particles. Rutherford knew that alpha particles are significantly more massive than electrons and positively charged. WebIn 1911 Rutherford made his greatest contribution to science with his nuclear theory of the atom. He had observed in Montreal that fast-moving alpha particles on passing through thin plates of mica produced diffuse images on photographic plates, whereas a sharp image was produced when there was no obstruction to the passage of the rays.
