Question

If the Thompson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been: (A) All of the α-particles pass through the gold foil without decrease in speed. (B) α-Particles are deflected over a wide range of angles. (C) All α-particles get bounced back by 180° (D) α-Particles pass through the gold foil deflected by small angles and with reduced speed.

As in Thomson model, protons are diffused (charge is not centred) α- particles deviate by small angles and due to repulsion from protons, their speed decreases.

Q. If the Thompson model of the atom was correct, then the result of Rutherford's gold foil experiment would have been:

All of the $α$ -particles pass through the gold foil without decrease in speed.

$α$ -Particles are deflected over a wide range of angles.

All $α$ -particles get bounced back by $18 0^{\circ}$

$α$ -Particles pass through the gold foil deflected by small angles and with reduced speed.

As in Thomson model, protons are diffused (charge is not centred) $α -$ particles deviate by small angles and due to repulsion from protons, their speed decreases.
