Aug 20, 2024 · Bohr model, description of the structure of atoms proposed in 1913 by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.
Niels Bohr proposed a model of the atom and a model of the chemical bond. According to his model for a diatomic molecule, the electrons of the atoms of the molecule form a rotating ring whose plane is perpendicular to the axis of the molecule and equidistant from the atomic nuclei.
Jul 16, 2020 · Danish physicist Niels Bohr proposed the model in 1913. The Bohr model was the first atomic model incorporating some quantum mechanics. Earlier models were the cubic model (1902), plum-pudding model (1904), Saturnian model (1904), and Rutherford model (1911).
What was Niels Bohr’s atomic model? Niels Bohr modeled the atom with electrons that could only have specific stable orbits. This model of the atom was the first to incorporate quantum theory.
Mar 12, 2024 · Niels Bohr's model, which depicted electrons orbiting the nucleus like planets around the sun, was awarded a Nobel Prize in 1922 despite being technically incorrect. Arnold Sommerfeld enhanced the Bohr model in 1916 with elliptical orbits.
Bohr 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.
Jul 12, 2013 · In July of 1913, Danish physicist Niels Bohr published the first of a series of three papers introducing this model of the atom, which became known simply as the Bohr atom. Bohr, one of the pioneers of quantum theory, had taken the atomic model presented a few years earlier by physicist Ernest Rutherford and given it a quantum twist.
