Question
- A. Atoms are solid and indivisible.
- B. Atoms contain a small, dense nucleus.
- C. Electrons are embedded in a positive sphere.
- D. Atoms have equal numbers of protons and electrons.
Answer
The correct answer is B: Atoms contain a small, dense nucleus..
Explanation
The correct answer is B: Atoms contain a small, dense nucleus.. This supports the learning objective "Describe the alpha particle scattering experiment carried out by Geiger and Marsden." 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: Atoms are solid and indivisible.; Electrons are embedded in a positive sphere.; Atoms have equal numbers of protons and electrons..
Common mistake
Misunderstanding Alpha Particle Scattering
Students often think that alpha particles are absorbed by the gold foil rather than passing through it.
Emphasize that most alpha particles pass straight through the foil, indicating that atoms are mostly empty space.
