What did Rutherford expect to happen to the alpha particles during the gold foil experiment?
Based on Thomson's plum pudding model, Rutherford predicted that most of the α particles would pass straight through the gold foil. This is because the positive charge in the plum pudding model was assumed to be spread out throughout the entire volume of the atom.
What will the alpha particles do when they hit the gold foil?
Q: What would you expect to happen when the alpha particles strike the gold foil? A: The alpha particles would penetrate the gold foil. Alpha particles are positive, so they might be repelled by any areas of positive charge inside the gold atoms.

Why did Rutherford expect the alpha particles?
Rutherford considered these observations and he concluded: The fact that most alpha particles went straight through the foil is evidence for the atom being mostly empty space. A small number of alpha particles being deflected at large angles suggested that there is a concentration of positive charge in the atom.

What evidence did Rutherford expect from his gold-foil experiment and how did the actually results contradict prevalent theory?
When Rutherford shot α particles through gold foil, he found that most of the particles went through. Some scattered in various directions, and a few were even deflected back towards the source. He argued that the plum pudding model was incorrect.
Why did Rutherford do the gold foil experiment?
Rutherford reasoned that if Thomson's model was correct then the mass of the atom was spread out throughout the atom. Then, if he shot high velocity alpha particles (helium nuclei) at an atom then there would be very little to deflect the alpha particles. He decided to test this with a thin film of gold atoms.
What conclusion did Rutherford gold foil experiment led to?
Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.
What are the conclusions of Rutherford experiment?
Most of the space inside the atom is empty. Therefore, most of the α-particles went through the gold foil without deflecting from their path. There is a positive tiny part in the atom in its centre, which deflects or repels the α-particles.
