WebBohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. Web21 de set. de 2024 · In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii.

But that model is a lot less scientific than it’s taken to be. To begin with, we can never have direct evidence of the Big Bang itself, and so if we are to accept it, it must be as a metaphysical, not a scientific hypothesis. Furthermore, the … cythere yohan
