Answer : Thomson proposed that: an atom consists of a positively charged sphere and the electrons are
embedded in it.The negative and positive charges are equal in magnitude. So, the atom as a whole is electrically neutral.Thomson's model of the atom fails to explain Rutherford's α-particle scattering experiment in which most of the fast moving α-particles passed straight through the gold foil.Only Some of the α-particles were deflected by the foil by small angles.Which clearly established atom has a lot of empty space and positive charge is concentrated in a very small volume within the atom.
