In this worksheet, we will practice describing the historical development of atomic models and the rationales, strengths, and limitations of each model.
Which theory of the atom came first: Rutherford’s nuclear model, Bohr’s orbital model, Dalton’s hard sphere model, or Thomson’s plum pudding model?
- ABohr’s orbital model
- BRutherford’s nuclear model
- CThomson’s plum pudding model
- DDalton’s hard sphere model
In the Geiger-Marsden experiments supervised by Ernest Rutherford (known as the Rutherford gold foil experiment), which type of particle was scattered by gold foil, proving that atoms contain dense nuclei?
- A particles
- B particles
- D particles
- EGamma rays
What step forward from Bohr’s orbital model of the atom was made by Schrödinger in his electron cloud model?
- AElectrons are moving within a positively charged sphere.
- BElectrons occupy shells with fixed radii.
- CThe nucleus contains particles with mass but no charge.
- DElectrons are spread out over space.
- EThe nucleus contains particles with mass and positive charge.
