WebL'esperimento di Rutherford: poche particelle alfa vengono deflesse dal campo elettrico del nucleo; la maggior parte di esse attraversa lo spazio vuoto dell'atomo.. Con la scoperta … 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 electrons surrounding a small, dense, positively charged nucleus. Given this experimental data, Rutherford naturally considered … 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 quantum jumps between orbital energy levels. … See more Niels Bohr said in 1962: "You see actually the Rutherford work was not taken seriously.

Debido a esto, Bohr decidió llevar a cabo un experimento con el fin de proponer un nuevo modelo.. Antes de llevarlo a cabo, Bohr ya tenía claro que los electrones se encontraban orbitando el núcleo del átomo, y sabía que estos no emitían … in the lower
