In Rutherford's alpha-particle scattering experiment, α\alphaα-particles were directed at a thin gold foil. Which of the following statements correctly describes an observation from the experiment and the conclusion drawn from it?
Most of the α\alphaα-particles passed straight through undeflected, showing that the nucleus has a positive charge.
A tiny fraction of the α\alphaα-particles were deflected by large angles, showing that the mass and positive charge of the atom are concentrated in a tiny volume.
No α\alphaα-particles were deflected, showing that the plum pudding model was completely correct.
All α\alphaα-particles were absorbed by the gold foil, showing that atoms do not contain any empty space.
