2020-05-03 · Atomic spectrum of hydrogen consists of a number of lines which have been grouped into 5 series :Lyman, Balmer, Paschen, Brackett and Pfund. Any given sample of hydrogen gas gas contains a large number of molecules. The line spectrum of the simplest element, hydrogen, was studied well before the turn of the century and the wavelengths of its lines were well known. In the visible range, a series of lines is observed at the following wavelengths (in nm): 656.279, 486.133, 434.047, 410.174, 397.007, 388.905, 383.539, and 379.790. Need help in Chemistry?

Line spectra of hydrogen

α line of Lyman series p = 1 and n = 2; α line of Lyman series p = 1 and n = 3; γ line of Lyman series p = 1 and n = 4; the longest line of Lyman series p = 1 and n = 2; the shortest line of Lyman series p = 1 and n = ∞ When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels. Those photons appear as lines. For this reason, though hydrogen has only one electron, more than one emission line is observed in its spectrum.

This image from NASA-Ames shows a hydrogen arc lamp fluorescing: Neils Bohr used the emission spectra of hydrogen to develop his model of the atom. In short, quantized energy levels release specific bands of light with unique colors.

Hydrogen Fine Structure When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. This splitting is called fine structure and was one of the first experimental evidences for electron spin.

With sodium, however, we observe a yellow color because the most intense lines in its spectrum are in the yellow portion of the spectrum, at about 589 nm. 25 rows 2015-11-03 What you would see is a small part of the hydrogen emission spectrum. Most of the spectrum is invisible to the eye because it is either in the infra-red or the ultra-violet.
