Bohr's theory can't explain the spectrem

WebUsing the Bohr model, we can calculate the energy of an electron and the radius of its orbit in any one-electron system. 9.1 Line Spectra Another paradox within the classical electromagnetic theory that scientists in the late nineteenth century struggled with concerned the light emitted from atoms and molecules. WebWe can use Bohr’s model of the atom to understand how spectral lines are formed. The concept of energy levels for the electron orbits in an atom leads naturally to an explanation of why atoms absorb or emit only specific energies or wavelengths of light. The Hydrogen Spectrum. Let’s look at the hydrogen atom from the perspective of the Bohr ...

WebOct 7, 2012 · In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation. Bohr’s model explained why atoms only emit light ... WebKey Concepts and Summary.
