What are the defects of Rutherford ‘S model?

Sunday, September 7, 2014

According to Rutherford’s model ,an atoms consist of a positive nucleus with the electrons moving around it in circular orbits. However it had been shown by J.C.Maxwell that whenever an electron is subjected to acceleration, it emits radiation and loses energy. As a result of this, its orbit should become smaller and smaller and finally it should drop into the nucleus by following spiral path. This means that atoms would collapse and thus Rutherford’s model failed to explain stability of atoms.Another drawback of the Rutherford’s model is says nothing about the electronic structure of the atoms i.e., how the electron are distributed around the nucleus and what are the energies of these electrons therefore, this model failed to explain he existence of certain definite lines in the hydrogen spectrum.
