In an experiment involving $\alpha$-particle scattering, $\alpha$-particles are aimed at a thin gold foil. The majority of the $\alpha$-particles pass directly through the foil, or are turned through only a small angle. A small number of $\alpha$-particles are turned through a large angle. Which statement cannot be deduced from this experiment?
- AAtoms are mostly empty space.
- BMost of the mass of an atom is concentrated in the nucleus.
- CThe nucleus of an atom contains protons.
- DThe nucleus of an atom is small compared to the size of an atom.
