Which of the following correctly states the conclusion drawn from the Rutherford-Geiger-Marsden experiment?
A. The nucleus of an atom contains protons and neutrons.
B. Protons and electrons have equal but opposite charges.
C. The nucleus contains nearly the entire mass of the atom.
D. Gold atoms absorb alpha particles.

本题详细解析:
Explanation: A. At the time of this experiment (1911), neither protons nor neutrons had been discovered. B. This experiment did not reveal anything about electrons. C. This is the correct answer. The conclusion from the alpha particle scattering experiment was that there are high concentrations of positive charge and mass in the middle of an atom, with most of the atom empty space. D. This experiment was not specific to gold. Gold foil was used in the experiment but the experiment was about the structure of matter in general. There was also no absorption observed.
