These orbits are quantized, meaning that electrons can only occupy certain discrete energy levels and not any energy level in between. Energy Levels: Bohr’s model suggested that electrons move around the nucleus of an atom in specific energy levels or orbits.Key points of niels bohr atomic model theory: His atomic theory, known as the Bohr model, was proposed in 1913 and played a crucial role in explaining the behavior of atoms and their spectral lines. Niels Bohr was a Danish physicist who made significant contributions to the understanding of atomic structure and quantum mechanics. The energy lost by the electron during the sudden transition is identical to the energy of the emitted light quantum. He argued that light only emitted from hydrogen atoms when an electron moved from an outer orbit to one closer to the nucleus. niels bohr atomic model was able to explain the series of discrete wavelengths in the hydrogen emission spectrum by restricting the orbiting electrons to a series of circular orbits with discrete radii. Bohr Model Class 11 and 12īohr model for Class 11 and 12 Students: Bohr changed his mind about the planetary electrons’ mobility to align the model with the regular patterns (spectral series) of light emitted by real hydrogen atoms. The German-born physicists James Franck and Gustav Hertz obtained direct experimental evidence for the existence of such discrete states in 1914. Only when electrons abruptly leap between permissible, or stationary, states do atoms absorb or release radiation. The properties of atomic electrons are described by the niels bohr atomic model and all of its successors in terms of a set of permissible (possible) values. It represented a significant break from earlier, classical representations. The niels bohr atomic model of the atom was the first to incorporate quantum theory and was the forerunner of entirely quantum-mechanical models. The niels bohr atomic model is a description of the structure of atoms, particularly hydrogen, proposed by Danish physicist Niels Bohr in 1913.
