Teachers, to get PLUS for your school, email [email protected] In this video, we look at the alpha scattering experiment. First we look at what the ancient Greeks thought about the structure of atoms and how this was disproven by the discovery of the electron. We then explore an early model of atomic structure called the plum pudding model. Next we look at the alpha scattering experiment. We explore how the alpha scattering experiment was carried out including why gold foil was used. We then look at how the results of the alpha scattering experiment told scientists that atoms are mainly empty space, with a central positive nucleus containing most of the mass of the atom and electrons around the edge. Finally, we look at how scientists replaced the plum pudding model with the nuclear model of atomic structure. This video is based on the AQA spec.
