Models of the atom 0.0 / 5 ? PhysicsRadioactivityGCSEEdexcel Created by: Jasmine.Li0278Created on: 27-11-18 20:32 What was J.J. Thompson's model of the atom called? The plum pudding model 1 of 6 What did the plum pudding model look like? It had negatively charged 'electron plums' embedded in a uniform, positively charged 'dough'. 2 of 6 What did the plum pudding model show in terms of an atoms charge? Both negative and positive charges existed in atoms and the atom had a neutral charge. 3 of 6 What did Rutherford's model of the atom look like? It must contain a very small, positively charged nucleus which electrons orbit. The atom is mostly empty space and most of the mass is at the nucleus. 4 of 6 How was Rutherfords Hypothesis proved? Geiger and Marsden fired alpha particles at gold film which showed some alpha particles scattered and some were undeflected. 5 of 6 What did the Bohr Model look like? Electrons had to orbit a positive nucleus in well deined energu level orbits, but could move between energy levels if they gained or lost energy. 6 of 6
