The plum-pudding atomic model, proposed by J Thomson in 1904, suggested that atoms were composed of a uniform positive sphere of matter with negatively charged electrons randomly distributed. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin. Start studying Plum Pudding Atomic Model. Since the overall atom is neutral, the plums (electrons) would be negatively charged and the pudding (protons) would be positively charged. Further experiments in 1909 produced results that could not be explained by the Plum Pudding model, so it was replaced by the nuclear model Examiner Tip For the exam you need to be able to describe the features of JJ Thomson’s Plum Pudding model, but you do not need to know how electrons were discovered (this is covered at A Level), or about. Thomson's discovery of the electron and the plum pudding model of the atom. The plum pudding model is an early 20th-century atomic model proposed by J Thomson that depicts the atom as a uniform sphere of positively charged 'pudding' with negatively charged 'plums' (electrons) embedded within it.

The plum pudding atomic theory … Plum pudding model - Model of the atom showing that negative electrons are embedded in a ball of positive charge. Plum pudding is an English dessert similar to a blueberry muffin. The Plum Pudding Model Thomson also knew that atoms are neutral in electric charge, so he asked the same question: How can atoms contain negative particles and still be neutral? He hypothesized that the rest of the atom must be positively charged in order to cancel out the negative charge of the electrons. Forefather of subatomic research : Thomson’s work laid the groundwork for future scientists to refine the model of the atom, leading to the understanding that atoms are made.
