Unformatted text preview: Nuclear Reactions 1. To investigate the composition of gold foil using alpha particles (i.e. to explain the model of an atom). Nuclear Reactions 2. The equipment used: θ α-source vacuum gold foil zinc sulphide detector Nuclear Reactions 3. Rutherford fired alpha particles through a piece of gold foil and used a zinc sulphide detector to detect the scattered alpha particles and their location. 4. Alpha particles were used as they would not become attracted to the nucleus. Nuclear Reactions 5. Rutherford found that 1. Most of the alpha particles passed through the gold foil undeviated, 2. A few alpha particles were deviated from their path but continued through the gold foil, and 3. A small number of alpha particles rebounded. 6. Rutherford concluded that 1. most of the atom was empty space, 2. The alpha particles were deviated from their original path due to positive charges within the atom, and 3. The atom had a positive nucleus where most of the mass was concentrated. Nuclear Reactions...
