One problem with Rutherford's model was that if electrons moved in such random orbits, they would emit electromagnetic waves, according to the laws of classical mechanics. No radiation was seen, and the release of radiation from the electrons would cause them to decay and lose energy. This would cause the electrons to spiral down to the nucleus, and destroy itself. This model said that all matter was unstable. Like Thompson's, Rutherford's model was still not able to explain atomic emission and absorption in the line spectra. He could not answer to why atoms produce light at specific, discreet wavelengths. He also could not explain why atoms emitted and absorbed at discreet wavelengths as opposed to bands of continuous wavelengths. Rutherford's discovery of the nucleus of the atom and his theory that electrons orbit around the positively charged nucleus led to Neils Bohr's idea that the electrons actually travelled in fixed energy levels, which did not cause electrons to lose energy while orbiting and also explained the light emissions of the atoms.

In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.
No one proposed it. It IS about the atomic number.
The modern atomic model is elaborated by Niels Bohr.

The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.
Ernest Rutherford's experiments on radioactivity led to the discovery of the atomic nucleus, laying the foundation for our understanding of the structure of atoms. His work ultimately paved the way for the development of nuclear physics and the harnessing of nuclear energy. Rutherford's research also had a significant impact on the field of chemistry, as it helped to establish the concept of isotopes.
Ernest Rutherford was an investigator of atomic theory, and it was his model of the atom, the one with the mass concentrated in the center, that replaced the J.J. Thompson model. Links are provided below.
