explain in detail about rutherford model of atom. and also write its limitations
Answers
Answer:
Rutherford model was based on experimental results . The features of Rutherford model was, 1. Relatively high central charge concentrated in very small volume as compared to rest of the atom and almost all mass of the atom recites in it. This would be called as nucleus of the atom .
2. Electron spin around the nucleus in a circular path.
DRAWBACKS :-
As before, Rutherford atomic model was also challenged and questioned by many. Rutherford atomic model failed to explain about the stability of electrons in a circular path.
As per Rutherford’s model, electrons revolve around the nucleus in a circular path. But particles that are in motion on a circular path would undergo acceleration, and acceleration causes radiation of energy by charged particles. Eventually, electrons should lose energy and fall into the nucleus. And this points to the instability of atom. But this is not possible because atoms are stable. Hence, Rutherford failed to give an explanation on account of this.
Answer:
Rutherford's Model of an Atom
Explanation:
Rutherford desined an experiment in that fast moving alpha particles are allowed to fall on an thin Gold coin.the gold foil was about 1000 atoms thick.
Observation
- Most of the fast moving alpha particles passed straight.
- some of them were deflected by small angles .
- Surprisingly one out of every 1200 particles appeared to be rebound.
Conclustion
- Most of the space inside the atom is empty.
- the positive charge of the atom occupies very little space .
- All of the Positive charge and the mass of the atom is concentrated in a small space .
Limitations
It donot expain the stability of an atom
