WebSep 16, 2024 · The solar system or planetary model of the atom was attractive to scientists because it was similar to something with which they were already familiar, namely the solar system. Figure 9.4. 3: Niels Bohr with Albert Einstein at Paul Ehrenfest's home in Leiden (December 1925). Unfortunately, there was a serious flaw in the planetary model. WebIn 1913 Bohr proposed his quantized shell show of the particle (see Bohr nuclear show) to clarify how electrons can have steady circles around the core. ... To cure the soundness issue, Bohr adjusted the Rutherford show by requiring that the electrons move in circles of settled measure and vitality. Explanation: hope it helps!
WebThe Niels Bohr Collected Works are now complete with the publication of Volume 12, Popularization and People (1911-1962). Niels Bohr is generally regarded as one of the most influential physicists of the twentieth century. The following are only some of the high points. In 1913, Bohr proposed a revolutionary model WebExpert Answer. 1. True, because Bohr assigned definite energy to each level. So, absorption of energy to go to a particular higher energy level, or emission of …. Classify each of the following statements about the Bohr model of the atom as True or False.

WebSep 21, 2024 · Bohr's Model. In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii.
WebJan 25, 2024 · Bohr proposed that electrons move around the nucleus in specific circular orbits. The radius of those specific orbits is given by, \(r = \frac {Ze^2}{4πε_0 mv^2}\) According to Bohr’s calculation, for the hydrogen atom, the energy for an electron in the specific orbit is given by the expression:
Web• Bohr's model of the atom would have been strengthened because Bohr proposed that electrons can have only certain energy values.
