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.
Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
Apr 2, 2014 · Niels Bohr was an accomplished physicist who came up with a revolutionary theory on atomic structures and radiation emission. He won the 1922 Nobel Prize in physics for his ideas and years...

Key points. Bohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr's model calculated the following energies for an electron in the shell, n : E ( n) = − ⋅ .
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). Ultimately, models based entirely on quantum mechanics replaced the Bohr model.
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.
