WebApr 2, 2014 · German physicist Wilhelm Conrad Röntgen had discovered X-rays just months before Rutherford arrived at Cavendish, and X-rays were a hot topic among research scientists. ... the alpha particle was ... WebThe only explanation for this was that the entire positive charge in an atom, the charge that would repel an alpha particle, must be concentrated in a very small area. An area that he called the nucleus. Because most of the alpha particles passed right through the atoms undeterred Rutherford concluded that most of the atom is empty space.

WebApr 9, 2024 · Rutherford (1902) segregated these by passing them between two plates with opposing charges. The positive charge, or “alpha” rays, were those that bent toward the negative plate. The negative charge-carrying objects that bent in the direction of the positive plate were known as (beta) rays.
