Bohr's theory pdf

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. WebSep 12, 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton.
