Q. If the Thompson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been:
JEE Main
JEE Main 2021
Structure of Atom
A
All of the $\alpha$-particles pass through the gold foil without decrease in speed.
B
$\alpha$-Particles are deflected over a wide range of angles.
C
All $\alpha$-particles get bounced back by $180^{\circ}$
D
$\alpha$-Particles pass through the gold foil deflected by small angles and with reduced speed.
Solution:
As in Thomson model, protons are diffused (charge is not centred) $\alpha-$ particles deviate by small angles and due to repulsion from protons, their speed decreases.
