Question 75

In the α\alphaα-particle scattering experiment, a beam of α\alphaα-particles is directed 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 α\alphaα-particles pass straight through with no deflectionInside the atom is mostly empty space
BMost α\alphaα-particles pass straight through with no deflectionThe nucleus has a large positive charge
CA tiny fraction of α\alphaα-particles are deflected through large anglesInside the atom is mostly empty space
DA tiny fraction of α\alphaα-particles are deflected through large anglesThe mass of the atom is distributed uniformly
