In bohr's model of hydrogen atom
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 quantum mechanics, a branch of physics, the Bohr modelis the model of the atomproposed by Niels Bohr. Bohr's model is useful only when discussing the behavior of a hydrogen atom. Bohr's model is extremely useful in describing the hydrogen emission spectrum.
