Detailed Solution

According to Thomson’s model of an atom the mass of the atom is uniformly distributed, the positive charge is uniformly distributed and in the positively charged sphere the electrons are uniformly distributed.
Thomson's atomic model states that an atom is composed of a positively charged sphere into which negatively charged electrons are implanted. Because electrons and protons have the same magnitude, an atom is electrically neutral as a whole. The Thomson model of an atom could not explain how a positive charge in the atom holds the negatively charged electrons. It couldn't explain the nucleus's position in an atom or the scattering of alpha particles.
