Question

hey friends please describe Rutherford Model

Answer 1

The Rutherford model is a model of the atomdevised by Ernest Rutherford. Rutherford directed the famous Geiger–Marsden experiment in 1909 which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model[1] for the atom, based on the experimental results, contained the new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom. This region would be known as the "nucleus" of the atom.

EXPLAIN RUTHERFORD MODEL OF AN ATOM

RUTHERFORD MODEL

Rutherford’s Experiment: Thomson’s student, Ernest Rutherford conducted an experiment using gold foil which disproved Thomson’s model. 

To study the structure of atom, Rutherford performed a thin gold foil scattering experiment. For his experiments Rutherford used a gold foil. He made a narrow beam of alpha particles to fall on the gold foil.

Observations made from the alpha ray scattering experiment
    •  Most of the alpha particles passed straight through the gold foil without getting deflected.
    •  A small fraction of the alpha particles were deflected through small angles.
    •  A few alpha particles bounced back.



Based on his observations, Rutherford proposed the nuclear model of an atom.

Postulates of Rutherford nuclear model:
    •  Positive charge is concentrated in the center of the atom, called nucleus.
    •  Electrons revolve around the nucleus in circular paths called orbits.
    •  The nucleus is much smaller in size than the atom.

Drawbacks of Rutherford’s Model
    •  The orbital revolution of the electron is not expected to be stable.
    •  According to Rutherford’s model, the electrons, while moving in their orbits, would give up energy.
