JEE Mains · Chemistry · STD 11 - 2. structure of atom
If the Thomson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been:
- A \(\alpha\)-Particles pass through the gold foil deflected by small angles and with reduced speed.
- B All \(\alpha\)-particles get bounced back by \(180^{\circ}\).
- C \(\alpha\)-Particles are deflected over a wide range of angles.
- D All of the \(\alpha\)-particles pass through the gold foil without decrease in speed
Answer & Solution
Correct Answer
(A) \(\alpha\)-Particles pass through the gold foil deflected by small angles and with reduced speed.
Step-by-step Solution
Detailed explanation
As in Thomson model, protons are diffused (charge is not centered) \(\alpha\)-particles deviate by small angles and due to repulsion from protons, their speeddecreases.
