Question
- A. The quantum model
- B. The nuclear model
- C. The planetary model
- D. The electron cloud model
Answer
The nuclear model
Explanation
The nuclear model was developed to explain the presence of a dense nucleus based on the results of the alpha particle scattering experiment.
Common mistake
Misunderstanding Alpha Particle Scattering
Students often think that alpha particle scattering proved the existence of electrons in the nucleus, rather than demonstrating the structure of the atom.
Focus on how the scattering showed that most of the atom is empty space and that a dense nucleus exists at the center, leading to the rejection of the plum pudding model.
