WebThe plum pudding model did not last long however, in 1909 a former pupil of Thomson’s, Ernest Rutherford discovered that the atom itself had a mass of positive charge at the centre, contrary to the plum pudding model. It was through the Geiger Marsden experiment that Rutherford made this conclusion. Web23 de dez. de 2024 · The model he proposed for the hydrogen atom had electrons moving around the nucleus, but only on special tracks with different energy levels. Bohr hypothesized that light was emitted when an electron jumped from a higher energy track to a lower energy track — that's what made hydrogen glow in a glass tube. pom benelux coldplay
