Why does hydrogen have the simplest bright line spectrum?
Although hydrogen has only one electron, it contains many energy levels. 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.
How is hydrogen bright line produced?
The bright line spectrum is produced by simply bursting energy into the element and bending the light that comes out. When energy hits an atom, the energy is soaked, causing an electron in an atom to jump to a higher level. This takes too much energy to support, however, so the electron falls back down.
What spectral lines does hydrogen have?
Balmer lines are historically referred to as “H-alpha”, “H-beta”, “H-gamma” and so on, where H is the element hydrogen. Four of the Balmer lines are in the technically “visible” part of the spectrum, with wavelengths longer than 400 nm and shorter than 700 nm….Balmer series (n′ = 2)

Why do hydrogen atoms have line spectrum?
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 orbit closest to the nucleus represented the ground state of the atom and was most stable; orbits farther away were higher-energy excited states.
Is hydrogen spectrum continuous?
Effect of the source on the continuous spectrum of hydrogen—The continuous spectrum of hydrogen is observed to be of similar character, although of differing intensity, in a number of sources, a Wood tube, an ordinary discharge tube, the separate striations of the positive column, the condensed spark in hydrogen at …
How many spectral lines does neon have?
Helium: slightly more complex than hydrogen, with one yellow line and a number in the blue. Neon: a very large number of lines in the red give neon signs their distinctive pink colors, but notice the two green lines. Argon: the pastel color of argon is due to a wide range of lines throughout the spectrum.
Why does neon have more spectral lines than hydrogen?
Neon has ten electrons. With ten electrons there are many more possible transitions of electrons from higher to lower energy levels and many more lines in the emission spectrum. Hydrogen only has one electron.
How is the bright line spectrum created?
Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…
Is hydrogen spectrum a bright line spectrum?
Line Spectra Although objects at high temperature emit a continuous spectrum of electromagnetic radiation (Figure 6.2. 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.
How many spectral lines does hydrogen spectrum have?
The electron energy level diagram for the hydrogen atom. He found that the four visible spectral lines corresponded to transitions from higher energy levels down to the second energy level (n = 2).
