Choose the correct option from the following options given below :
Options
- A
In the ground state of Rutherford's model electrons are in stable equilibrium. While in Thomson's model electrons always experience a net-force.
- B
An atom has a nearly continuous mass distribution in a Rutherford's model but has a highly non-uniform mass distribution in Thomson's model
- CA classical atom based on Rutherford's model is doomed to collapse.
- DThe positively charged part of the atom possesses most of the mass in Rutherford's model but not in Thomson's model.
Correct answer
C. A classical atom based on Rutherford's model is doomed to collapse.
Step-by-step solution
According to Rutherford's model, most of the mass of the atom is concentrated at the centre (nucleus) and the electron revolves around it.
As the electron is moving in a circular motion, it is accelerated. According to Maxwell accelerated charged particle loses its energy in the form of electro-magnetic radiation.
Therefore, a classical atom based on Rutherford's model is doomed to collapse.
