Question

Which conclusions are supported by Rutherford's α-particle scattering experiment?

G1 Physics · Accepted Answer

A is correct because most α-particles pass through the atom without significant deflection, showing that most atomic volume contains very little matter. B is correct because rare large-angle deflections require concentrated positive charge. C is correct because the large deflection of massive α-particles indicates a small, massive nucleus. D is not a conclusion of Rutherford's experiment. Quantized stationary states were introduced later in Bohr's model. Correct answers: A, B and C.
