What shortcomings in the atomic model of ernest Rutherford led to the development of niel's bohr's model?
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.

What did Ernest Rutherford add to are knowledge of atoms?
Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. He demonstrated that atoms are mostly empty space with a dense, positively charged nucleus at the center. This helped pave the way for further understanding of atomic structure and the development of the modern atomic theory.
