Rutherfords atomic model accounts for :

Sketch Rutherford's atomic model. Why Rutherford's model of the atom is called the planetary model ? (AS_(2))

Bohr's atom model assumes

Transpiration pull accounts for :

Write any three postulates of Rutherford's nuclear model of an atom.

Write any three postulates of Rutherford's nuclear model of an atom.

Compare Rutherford and Thomson's models of the atom on the following basis: • Where is the positive charge placed? • How are the electrons placed? • Are they stationary inside the atom or moving?

In the Rutherford’s nuclear model of the atom, the nucleus (radius about 10^(–15) m) is analogous to the sun about which the electron move in orbit (radius ~~ 10^(–10) m) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or farther away from the sun than actually it is? The radius of earth’s orbit is about 1.5 xx 10^(11) m. The radius of sun is taken as 7 xx 10^8 m .

In Sommerfield’s atomic model, corresponding to principal quantum number n = 3 there will be
