Question 32

In the Rutherford alpha-scattering experiment, alpha particles were directed at a thin gold foil. Which option correctly pairs an observation from this experiment with the corresponding conclusion about atomic structure?

A

Observation: Most alpha particles passed straight through. Conclusion: The nucleus is positively charged.

B

Observation: Most alpha particles passed straight through. Conclusion: Most of the atom is empty space.

C

Observation: A very small fraction of alpha particles deflected at large angles. Conclusion: Electrons orbit in distinct shells.

D

Observation: A very small fraction of alpha particles deflected at large angles. Conclusion: Positive charge is spread evenly through the atom.
