The Rutherford model of atom has neither addressed the process of radiation of atoms nor could it explain the stability of the atom in spite of the revolving electrons around the nucleus. According to electrodynamics the electron should radiate electromagnetic waves. A simple calculation shows that an electron starting from a circular orbit of the size of an atom will spiral into the nucleus by radiating away its energy in a very short time, about 10-8 s. This makes stability of the atom impossible, which is not the case.
His model could not explain the position of the electrons in an atom. Orbitals had not been discovered yet. He presumed the electrons were place similar to the plum-pudding model by J. J. Thompson. A key difference between the two models is the that Rutherford acknowledged the presence of the proton.
because jj thompson is a total freak.

The modern atomic model is elaborated by Niels Bohr.
its was Ernest Rutherford who proposed the planetary atomic model
mathematically it was calculated that for the Rutherford model to be stable it would require that 1000 or more electrons be in a single atom, but atoms only have (naturally occurring atoms) less than 100 electrons.
Ernest Rutherford. Added: I would think Neils Bohr here. Clarification: I think it was Rutherford. Bohr's work came after the "Rutherford Model". There are many places to read about this, eg Wikipedia " Rutherford Model". Certainly Bohr refined the Rutherford Model even before his quantum ideas for the hydrogen atom. That's why the "planetary model" is sometimes called the "Rutherford-Bohr Model."
Bohr model explain these spectra.

In Rutherford's model of the atom the electrons had a circular motion around the nucleus. By the laws of physics, if something is going in a circular motion then it must be accelerating and a particle that accelerates is losing energy. This means that the electrons that are revolving around the nucleus would eventually fall into the nucleus. Nucleus would eventually collapse. This does not happen therefore the Rutherford model was put aside.
any model on bohr model
Bohr formulated new explanation and theories to remove Rutherford defect in Rutherford atomic model thats why Bohr atomic model is better than Rutherford atomic model.
Rutherford's theory is known as the Rutherford model or Rutherford atomic model. It describes the structure of an atom as a dense positively charged nucleus surrounded by orbiting electrons.
The modern atomic model is elaborated by Niels Bohr.

Ernest Rutherford created the nuclear model of an atom!
This is the Rutherford model.
mathematically it was calculated that for the Rutherford model to be stable it would require that 1000 or more electrons be in a single atom, but atoms only have (naturally occurring atoms) less than 100 electrons.
