In the α-scattering experiment, few α-particles rebounded because
(a) Most of the space in the atom is occupied.
(b) Positive charge of the atom occupies very little space.
(c) The mass of the atom is concentrated in the centre.
(d) all positive charge and mass of the atom is concentrated in small volume.
Correct Answer: (d) all positive charge and mass of the atom is concentrated in a small volume.
Explanation: In the α-scattering experiment, few α-particles rebounded because all positive charge and mass of the atom are concentrated in a small volume known as the nucleus of the atom.
