Question 96

In the Rutherford alpha-particle scattering experiment, alpha-particles were fired at a thin gold foil.

Which row in the table correctly matches an observation from this experiment with the conclusion drawn from it?

ObservationConclusion
AMost alpha-particles passed straight through with no deflectionThe nucleus of the atom contains neutrons.
BMost alpha-particles passed straight through with no deflectionMost of the volume of the atom is empty space.
CA small fraction of alpha-particles deflected through large anglesThe atom is a solid charge-neutral sphere.
DA small fraction of alpha-particles deflected through large anglesElectrons orbit the nucleus in quantized energy levels.
