The Geiger Marsden Rutherford Gold Foil Experiment - IB Physics

The Geiger-Marsden Experiment (also called the Rutherford Gold Foil Experiment) disproved the plum pudding model of an atom and predicted instead that an atom has a small, dense nucleus surrounded by mostly empty space. This lecture explains how the experiment was done and what conclusions were drawn from it.

    Very interesting concept but that plum pudding looks quite unappetizing so frankly I'm glad I'm not surrounded by tiny versions of it lol

    I can see the experiment shows that there is/are some denser particle(s) in the atoms, but I don’t understand why it proves that the denser part is in the center of the pudding.

    Hello! I am currently studying for May 22 exams and was just wondering if the units are complete? I know that a couple of videos are missing from Unit 7: Atomic, Nuclear, and Particle Physics, but I wanted to know if maybe another Unit was missing a couple of videos or subtopics. I also wanted to take the time to thank you for all of your videos; they are the reason I might not fail physics haha

    I'm sceptical that the foil could be only single digits of atoms thick and even exist. Rutherford's 1911 paper quotes 0.00004 cm thickness for the foil, which would correspond to about 1400 atoms thick. Still extremely thin, but a little more realistic.
