Question
If the Thompson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been :
Choose an option
Show full solutionCorrect option: D
Correct answer
D-particles pass through the gold foil deflected by small angles and with reduced speed.
Step-by-step explanation
As in Thompson model, protons are diffused (charge is not centred) -particles deviate by small angles and due to repulsion from protons, their speed decreases.
