Need help with this pjhysics theoretical question:

The most surprising evidence from Rutherford’s experiment that disproved Thomson’s model was that:

	the alpha particles were able to pass through the gold foil
	most of the alpha particles were deflected by less than one degree
	a few alpha particles were scattered through very large angles
	the scattering was less random than expected

Expert Solution

Step 1: Introduction to the history of experimental atomic theory

Ernest Rutherford's gold foil experiment, conducted in 1909, marked a pivotal moment in the history of atomic theory. At the time, J.J. Thomson's "plum pudding" model of the atom, which depicted the atom as a uniform, positively charged sphere with dispersed negatively charged electrons, was widely accepted. This model suggested that alpha particles, which are positively charged helium nuclei, should pass through a gold foil with minor deflections, as the positive charge was thought to be evenly distributed throughout the atom.
