Question
Consider the following observations and their respective conclusions:
ObservationConclusion(i) Most of the fast moving α− particles passed straight through the gold foil.Most of the space inside the atom is empty. (ii) Some of the α−particles were deflectedby small angles.Positive charge of the atom occupies very littlespace.(iii) One out of every 12000 particlesappeared to rebound.Mass of an atom is spread in a very large volume.
Which of the above observation is/are not correctly matched with its conclusion?

Solution
The correct option is C
only (iii)
Rutherford designed an experiment in which fast moving alpha (α)-particles were made to fall on a thin gold foil. The observations and conclusions of the experiment are listed in the table given below.
ObservationConclusion(i) Most of the fast moving α− particles passed straight through gold foil.Most of the space inside the atom is empty. (ii) Some of the α−particles were deflectedby small angles.Positive charge of the atom occupies very littlespace.(iii) One out of every 12000 particlesappeared to rebound.All the positive charge and mass of the atomwere concentrated in a very small volume withinthe atom.
Hence, the correct answer is option (c).
