The results of Rutherford’s gold foil experiment disproved the model of the atom that his mentor and colleague had proposed. How does this example represent part of the necessary process for developing a scientific theory? could someone please help?? thank you!

Ernest Ruthorford's Gold Foil experiment proved the existence of a nucleus within an atom. With Geiger and Marsden, they OBSERVED the affect of alpha particles on matter. He determined through 'smart math :)' the location of the alpha particles. Through observation, Ruthorford HYPOTHESIZED that the (alpha) particles would penetrate thin metal foil. However, scattered due to the metal's subatomic particles. By using a sheet of gold, alpha particles would deflect in small proportions while the others would pass. Therefore, they concluded through TRIAL (testable) that there is volume at the center of an atom {fact} and where mass is most concentrated. It's a great example of scientific theory because it requires for a model to be well tested, verified and relates to nature's behavior through inductive reasoning.
