rutherford's model was compared with the solar system in which planets revolve around the sun in fixed circular paths.....but there is an important difference between the two .firstly whereas the electron and the nuclei are the microscopic particles,sun and planets were big bodies and hence newtonian law of motion do not apply to the motion of microscopic particles..(there is a separate branch called quantum mechanics for microscopic particles)
secondly sun and planets do not carry any charge like electrons and nuclei
according to Maxwell's electromagnetic theory whenever a charged particle like electron is revolving in a field of force like that of nucleus it losses energy continuously in the form of radiations...because when a particle is revolving it undergoes acceleration due to change in direction even if the speed remains constant..thus the orbit of the revolving electron will keep on becoming smaller and smaller following a spiral path and ultimately the electron will fall into the nucleus (calculations show that it will take 10^-8 second to spiral into nucleus)...in other words atom should collapse...however this does not happen and the atom is quite stable thus rutherford model could not explain the stability of atom..........
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
The Rutherford atomic model contain a central, positive, concentrated mass called atomic nucleus; around the nucleus are moving electrons.
The Bohr model of the atom describes electrons orbiting the nucleus in discrete energy levels, unlike the Rutherford model where electrons were expected to spiral into the nucleus. Both models incorporate the concept of a centralized positively charged nucleus surrounded by orbiting electrons, though Bohr's model adds the idea of quantized energy levels to explain the stability of atoms.
When Rutherford discovered the positive charge in an atom was concentrated in the nucleus, the neutron had yet to be discovered. There are no neutrons in Rutherford's model.
The Rutherford model involve a positive nucleus separated from electrons.
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
Rutherford's theory is known as the Rutherford model or Rutherford atomic model. It describes the structure of an atom as a dense positively charged nucleus surrounded by orbiting electrons.
Type your answer here... give the limitation of e-r model?how do you overcome this.
Ernest Rutherford created the nuclear model of an atom!
what are the limitations models
The Rutherford model proposed that an atom's positive charge is concentrated in a dense center called the nucleus. This model was based on the famous gold foil experiment conducted by Ernest Rutherford in 1909.

its was Ernest Rutherford who proposed the planetary atomic model
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.
Thompson discovered the electron and proposed his "Plum Pudding" model of the atom, while Rutherford refined it, moving the electrons to shells outside the nucleus. Google "Rutherford Model" and "Plum Pudding Model" for more info
