In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. The model is also referred to as the planetary model of an atom. The electrons orbit around the nucleus similar to how planets orbit ...
WebDec 23, 2024 · Niels Henrik Bohr (1885-1962) was a Danish physicist who developed the atomic model and won the 1922 Nobel prize in physics. "Bohr's model of 1913 for the hydrogen atom had circular electron orbits about the proton — like Earth orbits around the sun," says Herschbach. "Bohr had made use of a simple and regular pattern for the … WebIn atomic physics, the Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons. These electrons travel in circular orbits around the nucleus—similar in structure to the solar system, except electrostatic forces rather than gravity provide attraction.
