Rutherford Gold Foil Experiment Video Lessons

Concept:

# Problem: Part A. Watch the animation depicting Rutherford’s experiment and choose which of the following conclusions are correct.The atom is a very compact entity without any empty space.The atom contains a positively charged nucleus.A positive charge is spread equally over the atom.The mass of an atom is concentrated at the nucleus.Positive charge is condensed in one location within the atom.The majority of the space inside the atom is empty space.Check all that apply.In 1909, Ernest Rutherford performed an experiment to explore the atomic structure. In his experiment, he projected high-speed α particles onto a thin gold foil. He found that all α particles did not follow the same path. Most of the particles passed through the foil without any scattering, implying that most of the space in an atom is empty. Some particles were scattered at a large angle, and very few of them scattered back in the direction from which they had come. Based on these observations, Rutherford proposed an atomic model, which is known as Rutherford’s atomic model.
