The plumb pudding on the left, assumes that the neutrality of the atoms is due to the mixing of positive and negative charges, as in the image. Rutherfords gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Neutrons generally result from nuclear reactions, such as nuclear fission (as in nuclear reactors and fission-based nuclear weapons) and charged-particle activation of target atoms (as with some accelerator-produced radioisotopes). @annav - strong scattering is indeed the right answer, but it is elastic scattering. How did Rutherford's gold foil experiment differ from his expectations? As they got closer to the outer portion of the atom, the positive charge in the region was greater than the neighboring negative charges and the electron would be pulled back more toward the center region of the atom. In fact, the alpha particles were deflected much more than expected - some of them seemed to bounce almost straight back. He argued that the plum pudding model was incorrect. A small fraction of the alpha particles were deflected (scattered) through a large angle, indicating such a strong electric field within the atom that the positive charge must be concentrated in a small central corea core that is massive as well as small because the rebounding alpha particles showed no appreciable loss of kinetic energy.

Beta particles are fast-moving electrons with a very low mass and so have a high charge to mass density. Because the vast majority of the alpha particles had passed through the gold, he reasoned that most of the atom was empty space. Like charges repel, so the positive alpha particles were being repelled by positive charges. Suspicious referee report, are "suggested citations" from a paper mill? The electrons were somewhat mobile. Neutrons have no charge; hence it can't be reflected in the curved path, and it continues in the straight path. What happened to most of the alpha particles used in the gold foil experiment? Beta particles are negatively charged. A small number of alpha particles were deflected by large angles (> 4) as they passed through the foil. Since E is always positive, we need to look at only the right hand side of the plot.

Why are most alpha particles not deflected? Rutherford/GeigerMarsden gold foil experiment: what did they really think about alpha particles? It is worth emphasizing just how small the nucleus is compared to the rest of the atom. 4. According to the accepted atomic model, in which an atom's mass and charge are uniformly distributed throughout the atom, the scientists expected that all of the alpha particles would pass through the gold foil with only a slight deflection or none at all. D. empty space in the atoms present in the gold foil. How did Rutherford's gold foil experiment differ from his expectations? . Since some of the alpha particles (which are big in size) were deflected by large angles or bounced backwards, they must have approached some positively charged region responsible for the deflection. Why did the alpha-particles in Rutherford's experiment not collide with the electrons? Those that passes straight through did so because they didn't encounter any nuclei. For what atomic model did Rutherford's gold foil experiment provide? I was trying to aim more for a more intuitive answer, but yes, a cross section would be the technically correct way to approach this problem.
