Question

Write short notes on :-
a. Drawbacks of Rutherford's atomic model​

Answer 1

Answer:

The orbital revolution of the electron is not expected to be stable. According to Rutherford's model, the electrons, while moving in their orbits, would give up energy. This would make them slow down, gradually and move towards the nucleus. The electrons will follow a spiral path and then fall into the nucleus. Ultimately, the atom would collapse. But in reality the atom is stable.

Hope it helps you :)

Answer 2

Answer:

The positively charged particles and the majority of an atom's mass were contained in an incredibly small volume, according to the Rutherford atomic model. This part of the atom was dubbed a nucleus by him. The Rutherford model stated that the nucleus of an atom is surrounded by negatively charged electrons.

Explanation:

Drawbacks of Rutherford's atomic model​:

• The primary flaw in Rutherford's concept is the analogy of electrons to planets in the solar system. In motion, electrically charged particles lose energy (radiate energy). As a result, electrons revolving the nucleus should fall in a spiral path and collapse after losing energy.
• Atoms should be exceedingly unstable if this were true, but we know they are structurally stable. Rutherford's model was unable to account for this stability.
