The Alpha Scattering Experiment GCSE Physics

This video provides an in-depth look at Rutherford's experiment that led to the nuclear model of the atom - the Alpha Scattering Experiment. Before the nuclear model of the atom, physicists believed in Thomson's plum pudding model - the model that explained that the charges are equally spaced within the atom. • In order to probe the structure of the atom in more detail, alpha particles were fired at a very thin sheet of gold foil. Alpha particles are made of two protons and two neutrons, this means they're positively charged and very dense. The vast majority of the alpha particles made it through the foil, often being deflected in the process with a few being deflected back from the way they came. • This experiment led to the nuclear model of the atom: a dense, positive nucleus surrounded by shells of negative electrons. • Thanks for watching, • Lewis • Relevant for GCSE Physics 9-1 in the following exam boards: • AQA (including Trilogy) • Edexcel • CCEA (Physics only) • OCR A • OCR B • _____________________________________ • MY PHYSICS WEBSITES • Find even more videos organised by exam board and topic at: • GCSE Physics Online • ► https://www.gcsephysicsonline.com • A Level Physics Online • ► https://www.alevelphysicsonline.com • MY YOUTUBE CHANNEL • Your support in watching this video has been invaluable!
