WebFor the hydrogen atom (Z = 1), the smallest radius, given the symbol ao, is obtained from equation (4) when n = 1: ao ' (5) h2 4π2me2 '0.529 D This is called the Bohr radius. Using the definition of ao in equation (5), we can rewrite equation (4) to obtain a more compact form of the radius equation for any one-electron atom: r ' (6) n2a o Z 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. The dynamic … See more In atomic physics, the Bohr model or Rutherford–Bohr model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913, consists of a small, dense nucleus surrounded by orbiting electrons. … See more The Bohr model gives almost exact results only for a system where two charged points orbit each other at speeds much less than that of … See more Bohr's original three papers in 1913 described mainly the electron configuration in lighter elements. Bohr called his electron … See more The Bohr model gives an incorrect value L=ħ for the ground state orbital angular momentum: The angular momentum in the true ground state is known to be zero from experiment. … See more In the early 20th century, experiments by Ernest Rutherford established that atoms consisted of a diffuse cloud of negatively charged See more The Rydberg formula, which was known empirically before Bohr's formula, is seen in Bohr's theory as describing the energies of transitions or See more Niels Bohr said in 1962: "You see actually the Rutherford work was not taken seriously. We cannot understand today, but it was not taken seriously at all. There was no mention of it any place. The great change came from Moseley."
