The Bohr–Sommerfeld model (also known as the Sommerfeld model or Bohr–Sommerfeld theory) was an extension of the Bohr model to allow elliptical orbits...

It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.29177210544(82)×10−11 m. The Bohr radius is defined as a 0...

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...

In 1913, Niels Bohr proposed a model of the atom, giving the arrangement of electrons in their sequential orbits. At that time, Bohr allowed the capacity...
