Return to lower energy levels To be in the ground state all electrons must be in their lowest energy state; all excited atoms must lose energy. The lost energy appears in the form of light. Hope this helped :)

∙ 13y agoWhen you heat each element is will emit its own color and depending on the color it emmits that where is will be on the bright line spectrum.
*****************2nd Opinion***************
1. Heating a gaseous element can cause electrons to jump in energy (quantum jumps).
2. Almost immediately, the electrons lose that energy.
3. The lost energy shows up in the form of light, which is emitted from the atom.
4. Only certain energy jumps or falls are allowed by nature, so
5. Only certain frequencies (colors) are produced.
6. Those few colors make up the line spectrum of that element.

How did indium get its name?
its named after the bright indigo line in its spectrum
The Orion nebula m 42 is a hot thin cloud of glowing gas so its spectrum is?
A few bright lines against a dark background.
Cesium why blue in alkali?
Caesium metal is gives a bright blue solution when dissolved in liquid ammonia. The dissolving is believed to cause the production of caesium ions and a free electron. a similar blue colr is produced by sodium, potassium and rubidium. In aqueous alkali solutions caesium ion is colorless and therefore unless the anion is colored the solution is colorless.
What is sodium's color streak?
it is a silvery color, but can also be a white color
What element when lit causes a bright white glow?
Neon has a bright, white glow when it has been lit. Plutonium also has a bright glow, due to its reaction with oxygen.
What spectrum is produced by a hot gas under low pressure and appears in a series of bright lines?
Emission Spectrum
Image of emission or absorption spectrum of manganese?
This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
What kind of spectrum do dark lines appear against a bright a bright background of colors ranging from red to blue?
Dark-line spectrum is a "photo-negative" of emission spectrum. It is the gaps that appear in precisely the same location as corresponding bright lines. produced by a cool gas with a hot solid and you
The spectrum produced by glowing high-density gas is an a bright line emission b dark line absorption c chemical composition d temperature c continuous?
a Edit: The question is very mixed up, but I think I get the idea. It's obviously an emission spectrum. Because it is a high density gas the spectrum should be CONTINUOUS.
Why the positions of the dark bands on the absorption spectrum for an element correspond to the bright bands on the emission spectrum of the same element?
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
How is the bright light spectra of elements produced?
An emission or absorption line in a spectrum that arises when an electron moves between two energy levels in an atom. A jump to a higher level requires an input of energy, and produces a dark absorption line. A drop to a lower level releases energy, producing a bright emission line.
Star radiate different colors and lines based on their composition this is know as its?
It sounds like you're describing an emission spectrum. An emission spectrum will contain bright lines at specific colors, each of which is characteristic of a particular chemical element.
In which case will the woman see a just a spectrum that is almost entirely black except for few bright emission lines?
The spectrum that she will be observing is called an emission spectrum, in which electrons are excited to a higher energy state and then drop back down to the ground state, during which the electrons will emit photons of specific wavelengths, which will be observed as bright lines of color on what appears to be a black background.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
