Rutherford’s model of an atom could not explain the behavior of
electrons
According to Rutherford’s model of an atom, electrons revolve around the nucleus in fixed orbits. But, an electron revolving in circular orbits will not be stable because, during the revolution, it will experience acceleration. Due to acceleration, the electrons will lose energy in the form of radiation and fall into the nucleus. Hence, the atom would be highly unstable and would eventually collapse.
