Limitation of Rutherford model toward his postulation?

Answer 1

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..........

Answer 2

One limitation of Rutherford's model was that it couldn't explain the stability of atoms since his model suggested that electrons orbit the nucleus in a circular path, which would cause them to lose energy and spiral into the nucleus. This was due to the lack of reference to quantum mechanics, which was later addressed with the development of the Bohr model.

Answer 3

While the Rutherford model attributed the atom's charge and mass to a very small core, it did give a structure to the electrons and remaining Atomic Mass.
