WebSep 21, 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. WebIn Bohr’s model, radius an of the orbit n is given by the formula an = h2n2 ε 0 /π 2, where ε 0 is the electric constant. As Bohr had noticed, the radius of the n = 1 orbit is approximately the same size as an atom. With his …
WebThere are five principal models of the atom that have been proposed over time, each being related to the understanding of the atom at the time. The models are: Dalton ’s atomic model, Thomson ’ s atomic model, Rutherford ’ s atomic model, Bohr ’s atomic model, and the quantum atomic model.
