The Alpha Scattering Experiment - GCSE Physics

- This video provides an in-depth look at Rutherford's experiment that led to the nuclear model of the atom - the Alpha Scattering Experiment. Before the nuclear model of the atom, physicists believed in Thomson's plum pudding model - the model that explained that the charges are equally spaced within the atom.
In order to probe the structure of the atom in more detail, alpha particles were fired at a very thin sheet of gold foil. Alpha particles are made of two protons and two neutrons, this means they're positively charged and very dense. The vast majority of the alpha particles made it through the foil, often being deflected in the process with a few being deflected back from the way they came.
This experiment led to the nuclear model of the atom: a dense, positive nucleus surrounded by shells of negative electrons.

You baked a blueberry and lego muffin? That's true dedication to physics!
imagine eating the lego muffin by accident
I very carefully ate around the LEGO!
that muffin looks nice
Thanks alot. this helped :)
Since we know we're in a sea of undetectable dark matter but don't know where it's distributed and since everything in the universe from electrons to solar systems is in orbit with something else, why isn't the first assumption of how or why a photon acts like a particle but also as a ''wave packet'' for every physics student to think every photon might be in orbit with a dark matter particle pulling it into a polarizable axial or helical apparent wave as they travel?
There is also A collimator between the source of alpha particle and Gold Foil.
Hi. Im a radiology resident and trying to prepare myself for FRCR exam which is mostly based on Farr "physics for medical imaging"
Could you do a course on medical physics?
I have a whole section on my A Level website about medical imaging.
So what would have happened if the plum pudding model was correct? What where they expecting to see?
Great video thanks!
