Give the drawbacks of Rutherford 's model

Question

Answer

I am giving.the correct answer When electrons revolve around neuclus in circular paths they revolve their energy so one day they will die so atom is unstable but we know that atoms are much much stabe so his theory was discarded

Answer

1)This model could not explain the line spectra of the atoms.2)This model failed to explain the stability of atom.3)This model could not explain the electron structure of the atom.

Answer

Rutherford's model could not explain 👇👇👇👇👇👇👇👇👇👉👉1)could not explain the stability of atom..according to Maxwell electron loses its energy continuously in the form of electromagnetic radiations as result of of this the electrons loss energy at every turn and move more closer and closer to the nucleus following a spiral path .........the ultimate result will be that it will fall into the nucleus thereby making the atom unstable...2) if the electron loss energy continuously ...the observed spectrum should be continuous but the actual observed spectrum is line spectrum which consist of well defined lines of Definite frequencies (discontinuous) hence the loss of energy by electron is not continuous...

Drawbacks of Rutherford's Model

Rutherford's atomic model, also known as the planetary model, proposed by Ernest Rutherford in 1911, was a significant breakthrough in understanding the structure of atoms. However, the model also had several drawbacks that were later addressed by the Bohr model.

1. Failure to explain stability:
Rutherford's model failed to explain the stability of atoms. According to classical electromagnetic theory, an electron moving in a circular orbit should continuously emit energy in the form of electromagnetic radiation and spiral towards the nucleus. This would result in the collapse of the atom, making it unstable.

2. Absence of discrete energy levels:
The model did not account for the existence of discrete energy levels in an atom. It suggested that electrons could occupy any orbit around the nucleus without any restriction on energy levels. However, experimental evidence showed that only certain energy levels were allowed for electrons, as later explained by the Bohr model.

3. Lack of explanation for atomic spectra:
Rutherford's model could not explain the atomic spectra observed in experiments. When atoms are excited, they emit or absorb light at specific wavelengths, resulting in unique spectral lines. Rutherford's model did not provide a mechanism to explain why different elements produced different spectra.

4. Inability to explain the quantization of angular momentum:
The model did not address the quantization of angular momentum in atoms. Classical physics predicted that electrons should be able to occupy any orbit with varying angular momentum. However, experimental evidence showed that electrons have quantized angular momentum, which was later explained by the Bohr model.

5. Lack of explanation for the stability of larger atoms:
Rutherford's model could not account for the stability of larger atoms that contain multiple electrons. The electromagnetic repulsion between negatively charged electrons would cause the atom to collapse. However, in reality, atoms with multiple electrons are stable, which was later explained by the electron cloud model.

In conclusion, while Rutherford's model was a significant advancement in understanding the structure of atoms, it had several drawbacks that were later addressed by the Bohr model and subsequent developments in quantum mechanics. These drawbacks include the failure to explain stability, absence of discrete energy levels, inability to explain atomic spectra, lack of explanation for the quantization of angular momentum, and the inability to explain the stability of larger atoms.

Answer

when electrons revolve around the nucleus they move in a circular moion..which means they undergo acceleration..while acceleration they radiate energy and move in spiral motion and finally strikes the nucleus . this did'nt prove the stability of atom
