Question

what is the drawback of Rutherford's model of an atom​

Answer 1

What are the drawbacks of Rutherford model?

Originally Answered: Why is Rutherford's model wrong?

The model of the atom proposed by Rutherford assumes that the atom, consisting of a central nucleus and revolving electron is stable, much like sun-planet system, which the model imitates.

There are some fundamental differences between the 2 situations…

While the planetary system is held by Gravitational Force, the nucleus-electron system interact by Coulomb's Force as they are charged particles.

We know that an object moving in a circle is constantly accelerated by the centripetal force.

According to classical Electromagnetic Theory, an accelerating charged particle emits radiation in the form of Electromagnetic Waves!

That means, the energy of an accelerating electron should dwindle! The electron should then spiral inward and eventually fall into the nucleus!

That means our atom is not stable!

But the Cosmos we live in seems to be pretty stable :o

Further, the Electromagnetic Theory also states that the Frequency of the Electromagnetic Waves emitted by the revolving electrons is equal to the Frequency of Revolution. So, as the electrons spiral inward, their Angular Velocities and hence their Frequencies would change continuously! And so will the frequency of the light emitted!

That means they should be emitting a continuous spectrum. But ironically, a line spectrum is actually observed!

That's why we abandoned Rutherford's model of the atom and moved on…

It tells only a part of the story!

Answer 2

Answer:

Rutherford's model of atom is also known as Planetary model.

Explanation:

Rutherford Proposed that the nucleus is positively charged and electrons revolve round the nucleus in circular paths.

He also proposed that almost an atom is empty.

But there are some draw backs for this theory the important drawback is that when electrons revolve round the nucleus they loose energy and slip into the nucleus resulting in collapse of atoms.

This does not happen.
