- A. He suggested that electrons orbit at specific distances
- B. He discovered the neutron
- C. He proposed the plum pudding model
- D. He identified the nucleus as the center of the atom
Answer
The correct answer is A: He suggested that electrons orbit at specific distances.
Explanation
The correct answer is A: He suggested that electrons orbit at specific distances. This supports the learning objective "Explain why most alpha particles passing straight through gold foil suggested that atoms are mostly empty space." in The development of the model of the atom because it uses the correct atomic and nuclear radiation relationship for Atoms and isotopes. The other options are less suitable because they do not match the required The development of the model of the atom idea: He discovered the neutron; He proposed the plum pudding model; He identified the nucleus as the center of the atom.
Common mistake
Misunderstanding Atomic Structure
Students often think that atoms are solid and have no empty space.
Emphasize that most of an atom's volume is empty space, as demonstrated by the alpha particle scattering experiment.
