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

As per Rutherford's nuclear model of an atom , an atom has a very small sized nucleus with positive charge   inside and has  electrons revolving around this nucleus in well-defined orbits. Nearly all
the mass of an atom resides in the nucleus.
Rutherford's model of the atom failed to explain the the stability of the atom.  As any particle in a
circular orbit would undergo acceleration. During acceleration, revolving electron as charged particles would lose energy and finally fall into the nucleus. This may lead to a collapsed atomic structure, resulting in  very unstable atoms.Contrarily  atoms are mostly stable.
