Question

What are the limitations of Rutherford’s model of the atom?

Answer

The limitations of Rutherford’s model of the atom are:

Stability of the Atom: According to electromagnetic theory, a charged particle (electron) revolving in a circular orbit undergoes acceleration and radiates energy.
Collapse of the Atom: As the electron loses energy, it would spiral inwards and eventually fall into the nucleus. This would make the atom highly unstable.
Contradiction: This model fails to explain why atoms are stable, as matter exists and does not collapse.
