Web23 de dez. de 2024 · The model he proposed for the hydrogen atom had electrons moving around the nucleus, but only on special tracks with different energy levels. Bohr hypothesized that light was emitted when an electron jumped from a higher energy track to a lower energy track — that's what made hydrogen glow in a glass tube. Web27 de jan. de 2024 · The Bohr Model provides an incorrect value for the ground state orbital angular momentum. It makes poor predictions regarding the spectra of larger atoms. It does not predict the relative intensities of spectral lines. The Bohr Model does not explain fine structure and hyperfine structure in spectral lines. It does not explain the Zeeman Effect.
