In his gold foil experiment, rutherford shot alpha particles at very thin gold foil. what were the results of this experiment? most of the alpha particles bounced back from the gold foil to the observers. all of the alpha particles passed right through the gold foil. most of the alpha particles passed through the gold foil without deflection, except for a small percentage. the alpha particles became attracted to the electrons and got stuck in the gold foil.

1.) the modern atomic theory has been updated over the years as new observations of the atom have been made. what do these changes say about the strength of the modern atomic theory? a. the changes make the theory weaker because they demonstrate that the scientific community can't agree on the properties of atoms. b. the changes make the theory weaker because they demonstrate that the original atomic theory was flawed, so all resulting theories are also flawed. c. the changes make the theory stronger because it has been tested and edited multiple times, making it more durable. d. the changes make the theory stronger because each time the theory is changed, it becomes more popular. 2.) in rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. based on thomson's plum pudding model of the atom, what did rutherford expect to happen, and why? a. all the alpha particles would be deflected by the foil because of the even distribution of mass and charge throughout the atom. b. all the alpha particles would pass straight through the foil because of the even distribution of mass and charge throughout the atom. c. most of the alpha particles would become embedded in the foil because they are attracted to the negative electrons in the atom. d. some of the alpha particles would be deflected and some would pass through, because of the negative charge of the electron cloud.

After rutherford bombarded gold foil with alpha particles, he concluded that the volume of an atom is mostly empty space. which observation led rutherford to this conclusion? 1) some of the alpha particles deflected 180 degrees 2) the paths of deflected alpha particles were hyperbolic 3) many alpha particles were absorbed by gold nuclei 4) most of the alpha particles were not deflected

20 pts brainliest if thomson's model of the atom was correct, what would rutherford have seen in his experiments? all of the alpha particles would have passed straight through the foil. all of the alpha particles would have reflected off the foil. most of the alpha particles would have been absorbed by the foil. some of the alpha particles would have been deflected off the foil at large angles.
