WebBohr’s atomic model was the first known model of an atom that incorporated the quantum theory and also was the predecessor for the wholly quantum- mechanical models that were constructed many years later. Before 1913 it was thought of that an atom had a nucleus with electrons orbiting around it in a circular motion, but this was not the case.

WebThe Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. Bohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. WebIn Bohr’s formula the charge of the electron is raised to the fourth power. Two of those powers stem from the charge on the nucleus; the other two come from the charge on the electron itself. Bohr modified his formula for …
WebIn spectroscopy, the Rydberg constant, symbol for heavy atoms or for hydrogen, named after the Swedish physicist Johannes Rydberg, is a physical constant relating to the electromagnetic spectra of an atom. The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later … WebNiels Bohr (1885-1962) was a Danish physicist and winner of the 1922 Nobel Prize in Physics. Bohr began his work on the Manhattan Project after fleeing to Sweden from Denmark because of German occupation in 1943. Originally he was brought to London, working with the British Tube Alloys nuclear weapons development team.
