In the emission line spectra of hydrogen atom how many lines can be accounted for by all possible electron transitions between five lowest energy levels within.

Hydrogen molecule splits up into atoms. 2. These electrons absorb and energy electrons get excited. When these electrons come back to ground state they emit electromagnetic radiation of discrete frequencies. 3.

Hydrogen Predicted Fe II(UV)/Mg II ratios and fluxes strongly depend on non-abundance factors such as microturbulence, ionizing flux, and hydrogen density; all must be Partial Contents: Simplest Line Spectra and the Elements of Atomic Theory: 1.

1 Jul 2018 Laser-induced breakdown spectroscopy [14,15] measures optical emission from the micro-plasma, and the first few Balmer series hydrogen lines

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. Line spectra were first observed and studied in the latter half of the 19th century, but it was only in the 1920s that a full explanation was finally developed.

for the hydrogen evolution reaction (HER) due to their advantageous properties, including a. broad UV-Vis absorption spectrum and

" # $ % & = = = 2 d c b d sin d sin ab b c b ' ' The difference in emission lines are caused by the fact that helium has more electrons than hydrogen does. Hydrogen has only 1 while helium has 2. With more electrons being excited, more spectral lines will be observed. To calculate for helium, a Rydberg constant of 5.94x10 15 s -1 is used.

The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm. 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.

Diagram showing the absorption and emission spectra of the elements hydrogen and helium.

Hence, the photons of an emission spectrum represent a variety of possible energy levels. Emission spectra of the elements have complex structures; they become even more complex for elements with higher atomic numbers.

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.

Neon signs (or other gas discharge tubes) as used for advertising, sodium or mercury vapour lamps show atomic emission; the colours of fireworks are due to it.
