WebBohr followed Rutherford and thought that, in a hydrogen atom, an electron revolves about the proton at such speed that the Coulomb force between the electron and proton becomes just equal to the centrifugal force to keep this orbital motion. As discussed on the preceding page, this model was unstable with respect to the classical theory. WebJul 20, 2024 · According to Bohr’s theory two of the allowed orbits in the hydrogen atom have radii of 52.918 and 211.67 pm. Calculate the energy, the frequency, and the wavelength of the photon emitted when the electron moves from the outer to the inner of these two orbits. Solution

WebThis is called the Bohr frequency condition. We now understand that the atomic transitionenergy ¢E isequal to the energyof a photon, as proposed earlier by Planck and … WebOct 24, 2008 · When an atomic system emits or absorbs radiation, the frequency of the radiation is connected with the change of energy of the system by Bohr's frequency condition δ E = hv. This equation is usually applied to the transition of an atom from one … how deadly is a hippo

Bohr model - Wikipedia

WebThe equation AE hv is called the Bohr frequency condition and is the basic assumption that as the electron falls from one level to another, the energy evolved is given off as a photon of energy E hv. The energies and the energy differences are quantized, and so are the frequencies. WebFind out information about Bohr frequency condition. The law that the frequency of the radiation emitted or absorbed during the transition of an atomic system between two … WebThe above equation is Bohr's famous quantum condition. When an electron of mass m is confined to move on a line of length l with velocity v, the de-Broglie wavelength λ associated with electron is: λ= mvh = Ph Where P is Linear momentum P= λh= 2l/nh = 2lnh When electron revolves in a circular orbit of radius r then 2l=2πr how deadly is a redback spider
