Question 182: Atoms & Nuclei

Question

Choose the correct option from the following options given below :

Accepted Answer

An atom based on classical theory of Rutherford's model should collapse as the electrons in continuous circular motion that is a continuously accelerated charge should emit EM waves and so should lose energy. These electrons losing energy should soon fall into heavy nucleus collapsing the whole atom.

Answer

In the ground state of Rutherford's model electrons are in stable equilibrium. While in Thomson's model electrons always experience a net-force.

Answer

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.

Answer

A classical atom based on Rutherford's model is doomed to collapse.

Answer

The positively charged part of the atom possesses most of the mass in Rutherford's model but not in Thomson's model.
