Read each question carefully and answer to the best of your ability. For multiple-choice questions, select the best option. For short answer and fill-in-the-blank questions, provide clear and concise responses.
1. What was the primary goal of the Rutherford Gold Foil Experiment?
To discover the neutron.
To prove the existence of electrons.
To investigate the internal structure of the atom.
To measure the charge of a proton.
2. What type of particles were used as projectiles in the experiment?
Electrons
Protons
Alpha particles
Neutrons
1. Most of the alpha particles passed straight through the gold foil, suggesting that atoms are mostly .
2. A small fraction of the alpha particles were deflected at large angles, indicating the presence of a small, dense, positively charged within the atom.
3. The Rutherford model replaced the model of the atom.
1. The Rutherford Gold Foil Experiment confirmed the Plum Pudding Model of the atom.
True
False
2. Alpha particles are positively charged.
True
False
1. Describe the key observations made during the Rutherford Gold Foil Experiment.
2. Explain how these observations led Rutherford to propose the nuclear model of the atom.
Below is a simplified diagram representing the general setup of the Rutherford Gold Foil Experiment.
1. In the diagram above, draw the paths of three alpha particles:
a) One that passes straight through the gold foil.
b) One that is slightly deflected.
c) One that is heavily deflected (bounces back).
