Thomas and rutherford

    Cards (6)

    • Thomas was the first to use the term "nucleus"
    • Rutherford's experiment showed that most mass is concentrated at the centre, with electrons orbiting around it.
    • Rutherford's experiment involved firing alpha particles at thin sheets of gold foil, which were then detected by a fluorescent screen on the other side.
    • The majority of alpha particles passed straight through the gold foil without being deflected or scattered.
    • A small number of alpha particles were deflected from their path when they collided with atoms within the gold foil.
    • Protons have a positive charge and are found in the nucleus.
