Bohr model in 1921 [4] after Sommerfeld expansion of 1913 model showing maximum electrons per shell with shells labeled in X-ray notation. Until the second decade of the 20th century, atomic models were generally speculative. Even the concept of atoms, let alone atoms with internal structure, faced opposition from some scientists.

The theory would have correctly explained the Zeeman effect, except for the issue of electron spin. Sommerfeld's model was much closer to the modern quantum mechanical picture than Bohr's. In the 1950s Joseph Keller updated Bohr–Sommerfeld quantization using Einstein's interpretation of 1917, [6] now known as Einstein–Brillouin–Keller method.

[170] [171] On 7 October 2012, in celebration of Niels Bohr's 127th birthday, a Google Doodle depicting the Bohr model of the hydrogen atom appeared on Google's home page. [172] An asteroid, 3948 Bohr , was named after him, [ 173 ] as was the Bohr lunar crater , and bohrium , the chemical element with atomic number 107, in acknowledgement of ...
French physicist Jean Baptiste Perrin used the model in Einstein's paper to experimentally determine the mass, and the dimensions, of atoms, thereby giving direct empirical verification of the atomic theory. [citation needed] Niels Bohr's 1913 quantum model of the hydrogen atom. In 1913 Niels Bohr proposed a new model of the atom that included ...
Bohr Model of the Atom. The Bohr model, proposed by Niels Bohr in 1913, is a revolutionary theory describing the structure of the hydrogen atom. It introduced the idea of quantized orbits for electrons, combining classical and quantum physics. Key Postulates of the Bohr Model. 1.Electrons Move in Circular Orbits:
In 1910, Arthur Erich Haas further developed J. J. Thomson's atomic model in a paper [8] that outlined a treatment of the hydrogen atom involving quantization of electronic orbitals, thus anticipating the Bohr model (1913) by three years.
Model of the hydrogen molecule and its axial projection. In addition to the model of the atom, Niels Bohr also proposed a model of the chemical bond.. He proposed this model first in the article "Systems containing several nuclei" [1] - the third and last of the classic series of articles by Bohr, published in November 1913 in Philosophical Magazine.
