Question
- A. Atoms are mostly empty space
- B. Atoms are solid and indivisible
- C. Atoms contain only protons
- D. Atoms have no charge
Answer
The correct answer is A: Atoms are mostly empty space.
Explanation
The correct answer is A: Atoms are mostly empty space. This supports the learning objective "Describe how alpha scattering evidence led to the nuclear model replacing the plum pudding model." 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; Atoms contain only protons; Atoms have no charge.
Common mistake
Confusing Models
Students often confuse the plum pudding model with the nuclear model, thinking they describe the same structure of the atom.
To fix this, students should focus on the key differences: the plum pudding model depicts a positive sphere with electrons embedded, while the nuclear model shows a dense nucleus with electrons orbiting around it.
