Describe Rutherford's atomic model.

(N/A) On the basis of his observations and conclusions,Rutherford proposed the nuclear model of the atom. According to this model:
$(i)$ The positive charge and most of the mass of the atom are densely concentrated in an extremely small region,which Rutherford called the nucleus.
$(ii)$ The nucleus is surrounded by electrons that move around it at very high speeds in circular paths called orbits.
$(iii)$ Rutherford's model resembles the solar system,where the nucleus acts like the sun and the electrons act like the revolving planets.
$(iv)$ Electrons and the nucleus are held together by electrostatic forces of attraction.
