Question

what were limitation of Rutherford Model of atom ​

Answer 1

Limitations of Rutherford model

•An atom contains nucleus in it and also electrons revolving . So both should attract each other . But Rutherford explained that the electrostatic attraction is balaanced by centrifugal force allowing electron to revolve .

•But according to maxwell electromagnetic theory if a charged particle moves in electric or magnetic field of another charged particle it loses energy and falls in to the nucleus within a few milliseconds following a spiral path so an atom should be unstable . But an atom is quite stable .

•It didn't explain the arrangements of electrons in various shells .

☆$\red {HELLO\:DEAR}$☆

According to Rutherford’s model of an atom, electrons revolve around the nucleus in fixed orbits.

But, an electron revolving in circular orbits will not be stable because during revolution, it will experience acceleration.

Due to acceleration, the electrons will lose energy in the form of radiation and fall into the nucleus.

In such a case, the atom would be highly unstable and collapse.
