Bohr postulates of hydrogen spectrum

WebKey Concepts and Summary. Bohr incorporated Planck’s and Einstein’s quantization ideas into a model of the hydrogen atom that resolved the paradox of atom stability and discrete spectra. The Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. WebBohr’s Atomic Model, proposed by Neil Bohr, was based on Planck’s quantum theory of radiation. In order to overcome the limitations of Rutherford’s atomic model and to explain the line spectrum of hydrogen, Bohr’s Atomic Model proved to work as a remedy for the stability problem. However, Bohr’s atomic model failed to explain about the atomic …
