What Was Wrong With Rutherford's Model of the Atom
However Maxwell explained accelerated charged particles release electromagnetic radiations. He also agreed with Nagaoka that the electrons move in circular orbits outside the nucleus.

The distribution of electrons in the orbits was not given by Rutherford.
. He needed to find out why the fall into the nucleus but instead he guessed that electrons are not stationary but are revolving around the nucleus. The main problem with Rutherfords model was that he couldnt explain why negatively charged electrons remain in orbit when they should instantly fall into the positively charged nucleus.

What disproved the plum pudding model. This is wrong because the electrons are shown in stable orbits and they. Therfore the electrons are not accelerating they are merely in an non-symmetic orbit around the nucleus.
Thus the concept of orbitals is thrown out. In 1911 Rutherford showed that Thomsons model was wrong. The nucleus is much smaller in size than the atom.
Rutherfords model of atom was wrong because the presence of electrostatic attraction between the nucleus and the electrons. The electrons should fall into the nucleus but they didnt. The electron would lose energy and fall.
Far from the nucleus are the negatively charged electrons. The electrons are distributed around the nucleus and occupy most of the volume of the atom. According to Rutherfords postulate electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit.
Atomic spectra of hydrogen were proposed by Bohr. But the Rutherford atomic model used classical physics and not quantum mechanics. It was given by Bohr and Bury.
It is a stable model of atom that resembles our solar system. The fatal flaw in Rutherfords model is that it contains charges that are accelerating. This model of an atom was developed by Ernest Rutherford a New Zealand native working at the University of Manchester in England in the early 1900s.
This meant that an electron circling the nucleus would give off electromagnetic radiation. The charges are on the electrons and the acceleration is due to the electrons always changing direction as they move around their orbits. Rutherfords model shows that an atom is mostly empty space with electrons orbiting a fixed positively charged nucleus in set predictable paths.
Rutherford disproved the Plum Pudding Model of the. Although the early atomic models were inaccurate and failed to explain certain experimental results they were the base for future developments in the world of quantum mechanics. 2 It couldnt be extended to multi-electron systems.
Rutherfords atomic model became known as the nuclear model. This problem would be solved by Niels Bohr in 1913 discussed in Chapter 10. 1 According the the uncertainty principle the exact position and momentum of an electron is indeterminate and hence the concept of definite paths as given by Bohrs model is out if question.
In the nuclear atom the protons and neutrons which comprise nearly all of the mass of the atom are located in the nucleus at the center of the atom. Rutherfords model has a centralized nucleus that contains protons and neutrons with orbiting electrons. One of the drawbacks of the Rutherford model was also that he did not say anything about the arrangement of electrons in an atom which made his theory incomplete.
Rutherfords model was unable to explain the stability of an atom. The distribution of positive and negative particles was not uniform. Rutherford showed that the atom contains a small massive positively charged nucleus.
