In the alpha-particle scattering experiment, α\alphaα-particles were fired at a thin gold foil to investigate the structure of the atom. Which statement correctly describes an observation from this experiment and its correct explanation?
Most α\alphaα-particles passed straight through because they were pulled by the gravitational attraction of the gold nuclei.
A small fraction of the α\alphaα-particles were deflected through large angles because they experienced a strong electrostatic repulsion from the concentrated positive charge in the nucleus.
Some α\alphaα-particles were attracted to the nucleus by the strong force acting on neutrons.
All α\alphaα-particles were absorbed by the gold foil because the atoms of the gold foil are solid and have no empty space.
