WebJan 1, 2024 · A line emission spectrum is caused when energy is added to an atom. This added energy causes the electrons in the atom to jump up energy levels. When this happens, the atom is in an excited... WebFor most elements, there is a certain temperature at which their emission and absorption lines are strongest. The lines you see in a star's spectrum act like thermometers. Some compounds, like titanium oxide, only appear in the spectra of very cool stars. Others, like helium, appear only in the spectra of very hot stars.

WebAug 10, 2015 · The brightness of the emission lines can give us a great deal of information about the abundance of hydrogen present. This is particularly useful in a star, where … WebThis emission line is called Lyman alpha. It is the strongest atomic emission line from the sun and drives the chemistry of the upper atmosphere of all the planets, producing ions by stripping electrons from atoms and molecules. maruggi sarezzoWebKensi: “Emission lines are created in hot sources, like a fluorescent lamp. Absorption lines are made when light passes through a colder source like gas clouds, and the gas absorbs particular wavelengths of light.” dataqi chronicles

"WebThe correct answer is choice E, which is line E. The use of emission and absorption spectra is helpful for identifying unknown gases, but unknown gases are rarely made up of one element. When looking at a mixture of gases, the spectrum lines for all the gas constituents show up, as seen in the diagram below. " - Emission lines of elements

Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light. Analysis of this light, with the help of a spectroscope gives us a discontinuous spectrum. A spectroscope or a spectrometer is an instrument which is used for separating the components o… WebHeavier elements have more electron energy levels so they have more possible transitions and a denser thicket of emission lines. But for the most common elements like carbon and nitrogen and oxygen and silicon, the spectral lines fall in the same region of the electromagnetic spectrum. Most of the useful emission lines fall in the decade of ...
