Question

question 17 (1 point)
which observation did rutherford make as part of his gold foil experiment that was inconsistent with thomsons blueberry muffin model of the atom?
some alpha particles were not detected after scattering.
none of the above.
some alpha particles were deflected at various angles.
most alpha particles passed straight through the gold foil.

Explanation:

Brief Explanations

Rutherford's gold foil experiment involved shooting alpha particles at a thin gold foil. Thomson's plum - pudding (blueberry muffin) model assumed a uniform distribution of positive charge and electrons within the atom. If Thomson's model were correct, alpha particles (positively charged) should mostly pass through with only small deflections. However, in Rutherford's experiment, some alpha particles were deflected at large angles. This was inconsistent with Thomson's model. The option "Some alpha particles were not detected after scattering" is not a key observation against Thomson's model. The option "Most alpha particles passed straight through the gold foil" was consistent with both models (as in Thomson's model, the atom was mostly empty space in a sense, but with a uniform charge distribution). The key inconsistent observation was large - angle deflections. Since the given options do not have the correct key observation (large - angle deflections), the answer is "None of the above".

Answer:

None of the above.
