The nuclear model of the atom — practice question

The scattering of alpha-particles by a thin gold foil gives these observations. • The majority of the alpha-particles go through the foil. • The majority of the alpha-particles are almost not deflected. • A small proportion of the alpha-particles are deflected by large angles. • A very small proportion of the alpha-particles rebound from the foil. From these observations, which conclusion is not supported?

  • AMost of the mass of the gold atom is in its nucleus.
  • BMost of the atom is empty space.
  • CThe nucleus consists of protons and neutrons.
  • DThe nucleus must be charged.
