25 de abr. de 2024 · J.J. Thomson, born Joseph John Thomson in 1856, was a British physicist renowned for his discovery of the electron in 1897. Working at the Cavendish Laboratory at the University of Cambridge, Thomson demonstrated through his experiments with cathode rays that atoms are not indivisible as previously thought, but contain smaller particles.
25 de abr. de 2024 · J.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom. He developed the "plum pudding" model of the atom.
7 de mai. de 2024 · Joseph John Thomson proposed this model in 1904 and pictured atoms that are a bit like a classic British dessert. In this model, the atom is imagined as a “pudding” of positive charge with negative electrons scattered throughout, like plums in a pudding.
