Defects of Rutherford Model
Defects of Rutherford Model
Limitations of Rutherford’s Model of an Atom:
1. Rutherford had proposed that electrons revolve at high speed in circular orbits around a positively charged nucleus. But, such a model has a defect. To remain in a circular orbit the electron would have to be accelerated centripetally or radially. But, according to electromagnetic theory, if a charged body (electron) is accelerated around another charged body (nucleus) then there would be a continuous radiation of energy from the moving body. This loss of energy would slow down the speed of the electron and eventually the electron would fall into the nucleus. But, such a collapse does not occur—Rutherford’s model could not explain why.
2. Rutherford’s model could not explain the distribution of electrons in the extra nuclear portion of the atom.

10thIt was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
Eshan Arora
8thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.

8thIt was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
Cheshta
10thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
Archit Segal
7thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Hiya Gupta
8thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
