Solution
The correct option is C most of the atom is empty As most of the mass of an atom is present in the nucleus and since the volume the of nucleus is very small (only a minute fraction of the total volume of the atom) when compared to the volume of the atom. So, most of the α-particles pass through the atom without any deviation.
