How did Bohr change the Rutherford model of the atom?

Answer 1

Answer 1:

He improved on Rutherford's model by showing that electrons don't spiral inward to the core of the nucleus. Instead the electrons are on a set course.

Answer 2:

Another significant advantage of Bohr's model over Rutherford's, as well its accounting for the stability of atoms (as noted in the previous answer), was its ability to account for the observed wavelengths of the spectral lines, at least for hydrogen.

Although some aspects of the model were unsatisfactory (its rather ad hoc nature, the difficulty in applying it to multi-electron atoms, etc.), this remarkable agreement with experiment was a strong indication that Bohr's thinking was along the right lines. As we now know, Bohr's basic postulates were quite correct: the orbital angular momentum of electrons is indeed quantised, and electrons transition between allowed states by absorbing or emitting photons. Both of these assumptions became predictions of the quantum theory which was soon to follow.

Answer 2

Bohr's model was able to explain the reason for motion of electrons around the nucleus and why the electrons do not fall in the nucleus even when they move in circular motion and accelerate and loose energy.

This was the factor which was not explained by the Rutherford.

Answer 3

Niels Bohr introduced the notion of electronic orbits.

Answer 6

It established that a large volume of space surrounds the atomic nucleus.

Answer 7

The main difference between Thomson and Rutherford model of atom is that Thomson model does not give details about the atomic nucleus whereas Rutherford model explains about the nucleus.
