Drawbacks of rutherford atomic model 1) Electrons would revolve and thus undergo acceleration,during acceleration they would radiate energy 2) Electons would then lose energy and fall into the nucleus 3)If this were so, they would be unstable but as we know today atoms are quite stable.
Drawback of Rutherford atomic model: It can't explain the stability of an atom. This model could not explain the motion of electron in circular orbits. A charged particle would release energy during acceleration and eventually, it will fall into the nucleus.

He called this region of the atom as a nucleus. Rutherford's model proposed that the negatively charged electrons surround the nucleus of an atom. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. He named these circular paths as orbits.
Rutherford drawback was - He said that electrons moves in a circular path around the nucleus and as we all know that every body which moves in a circluar path will go through under accleration so electrons will also go through under acclerstion and will rediate (losse) energy because of which it will fall on nucleus and destroy it by which matter will become unstable
Well yes, Rutherford did state that electrons revolve around the nucleus in circular orbits.. However, since electrons are charged species (negatively charged) and according to Maxwells electromagnetic theory, any particle undergoing circular motion will accelerate. Hence, it will radiate energy..,hence, based on similar principles, if electron was to revolve around the nucleus without any specifications, which wasn't specified by Rutherford, would eventually lose energy and fall into the nucleus. However, in 1913, Bohr did come up with an atomic model to overcome the shortcomings of Rutherfords atomic model.
7:36 mam the anode rays were not given by anode they were made from the ionisation of gas present in the tube the ionisation occured due to cathode rays
Postulates of Bohr's model of atom are follows:- 1) He said that the electron revolve in descrete orbit. 2) while revolving in the orbit do bot radiate their energy thus electron do not fall down in the nucleus. 😮😮😮😮😮
1:18:17 1 only special orbits called discrete orbits are allowed inside the atom 2 why revolving in these discrete orbits atoms will not radiate energy
Drawbacks of Rutherford models of atom are follows:- 1) The electron revolve around the nucleus an radiate their energy and finally fall in the nucleus 😮😮😮😮
