Question
What was the main conclusion drawn from the alpha particle scattering experiment conducted by Geiger and Marsden?
Answer
The main conclusion was that most of the atom is empty space, as most alpha particles passed straight through the gold foil. Additionally, the deflection of some alpha particles indicated that a small, dense, positively charged nucleus exists within the atom.
Explanation
This question tests the understanding of the significance of the alpha particle scattering experiment in the development of atomic theory. The answer highlights the key findings that led to the nuclear model of the atom, distinguishing it from earlier models.
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.
