Spectral Lines of Hydrogen 2018-01-22T07:45:16+00:00

Bohr’s model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy is unchanged.

The change in energy, ?E, then translates to light of a particular frequency being emitted according to the equation E=hv. Recall that the atomic emission spectrum of hydrogen had spectral lines consisting of four different frequencies.

Based on the wavelengths of the spectral lines, Bohr was able to calculate the energies that the hydrogen electron would have in each of its allowed energy levels.

Bohr’s model was a tremendous success in explaining the spectrum of the hydrogen atom. Unfortunately, when the mathematics of the model was applied to atoms with more than one electron, it was not able to correctly predict the frequencies of the spectral lines.

Summary
Emission lines for hydrogen correspond to energy changes related to electron transitions.
The Bohr model works only for the hydrogen atom.
