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.
Check out my channel for lecture videos on the entire IB physics curriculum organized by topic.

    That's not the average velocity, it's the root mean squared velocity. The average velocity in a Maxwell-Boltzmann distribution is related to the root mean squared velocity by: E[v] = √(8/(3π))·√E[v²] So, the actual average velocity of the particle in the first problem is ~419m/s

    if anyones finding it hard to understand his working out for the examples, this video explaining moles really helped me (ruclips.net/video/0KPaj8UbP0I/видео.html). Just do n x avagadros constant = N (n = number of moles in substance & N = number of atoms in substance) Then just understand that the number of moles in a substance (n) is equal to the mass of the substance divided by the nucleon number (atomic mass). So basically the formula is (mass of substance/nucleon number) x avagadros constant = number of atoms in substance
