Niels Bohr explained the line spectrum of the hydrogen atom by assuming that the electron moved in circular orbits and that orbits with only certain radii were allowed. Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius.

The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom.

Hydrogen molecules are first broken up into hydrogen atoms (hence the atomic hydrogen emission spectrum) and electrons are then promoted into higher energy levels. Suppose a particular electron is excited into the third energy level.

What is Hydrogen spectrum? The hydrogen spectrum is an important piece of evidence to show the quantized electronic structure of an atom. The hydrogen atoms of the molecule dissociate as soon as an electric discharge is passed through a gaseous hydrogen molecule.

Atomic Line Spectra. The spectrum of hydrogen atoms, which turned out to be crucial in providing the first insight into atomic structure over half a century later, was first observed by Anders Ångström in Uppsala, Sweden, in 1853. His communication was translated into English in 1855. Ångström, the son of a country minister, was a reserved ...

Measuring the positions of the spectral lines remains today a significant test of the' predictions of the quantum theory. The most recent advances in the anal ysis of the spectrum can be attributed to a new tool of spectroscopy: the laser.

2022年3月23日 · As we know electrons always try to remain in their lowest energy level, the excited electrons go back to their original level and emit radiation in this process. This phenomenon explains the emission spectrum via hydrogen, sometimes known as a hydrogen emission spectrum.

2025年1月25日 · The hydrogen spectrum refers to the spectrum of light emitted or absorbed by hydrogen atoms. It is an example of the line emission spectrum or atomic emission spectrum. When an electric discharge is passed through hydrogen gas contained in a discharge tube under the low pressure, the hydrogen atoms absorb energy.
