This phenomenon was so unexpected that Rutherford later stated it was as incredible as firing a 15-inch shell at a piece of tissue paper and having it bounce back to hit you. Thomson’s “plum pudding” model, which depicted the atom as a diffuse sphere of positive charge with electrons embedded within it, much like plums in a pudding.
Why the Rutherford Experiment Shocked Scientists and Upended Atomic Theory
These particles then collided with an extremely thin gold foil, typically only a few hundred atoms thick, ensuring that the particles would pass through with minimal interactions. Limitations and Legacy of the Model More perspective on Rutherford atomic model experiment can make the topic easier to follow by connecting earlier points with a few simple takeaways.
Expected Results Based on the Plum Pudding Model According to the plum pudding model, the alpha particles should have passed through the gold foil with only minor deflections. Interpretation and the Nuclear Model Rutherford interpreted these surprising results in 1911, proposing a revolutionary model of the atom.
Why Rutherford's Experiment Surprised Scientists and Changed Atomic Models
By counting these flashes using a microscope on a turntable, the researchers could map the angles at which the particles were deflected, providing the first empirical data on atomic structure. Scientists expected the particles to exit the foil at small angles relative to their original trajectory, with virtually no particle experiencing a dramatic rebound.
