The Bohr model did an excellent job of explaining the spectrum of a hydrogen atom. By incorporating a Z 2 term into the equation, which adjusted for the increase in the attraction between an electron and the nucleus of the atom as the atomic number increased, it could even explain the spectra of ions that contain one electron, such as the He + , Li 2+ , and Be 3+ ions.

In the early twentieth century, his Institute for Theoretical Physics at the University of Copenhagen, in Denmark, was a center for some of the most important revolutionary thinking in formulating and studying the discoveries and insights related to the growing information about the quantum realm. Bohr Model. The Bohr model provides a theoretical framework for understanding line spectra. If a photon of light is absorbed its energy (h\( u\)) is transferred to an electron which jumps from a low energy orbit to a high energy orbit, and the absorption spectral lines are correlated to wavelengths associated with the frequency of that light (C=\(\lambda u\)).
