The nuclear model of the atom — practice question

The diagram illustrates $\alpha$-particles striking a thin metal foil. How does the way these particles move provide evidence for the nuclear atom?

  • AMost particles passing through with minimal deflection shows that the atom is mostly empty space.
  • BMost particles passing through with minimal deflection shows that the mass of the atom is uniformly distributed.
  • CLarge deflections of some particles shows that the atom is mostly empty space.
  • DLarge deflections of some particles shows that the charge in the atom is uniformly distributed.
