Give reasons.

In Rutherford's experiment, some alpha rays collide with the gold sheet and are turned back.

In Rutherford’s experiment, some alpha rays collide with the gold sheet and are turned back because:

i. The atom might contain positively charged particles.

ii. The space occupied by the positive charge is very small in the atom.

iii. Hence, when alpha rays come closer to this point, they suffer a force of repulsion and deviate from their paths and turned back.
