How is it possible to identify an element by looking at its spectrum?

Each element has a unique adsorption and/or radiant spectrum.
If you compare the spectrum you get with a list of known spectrums you can make a match.

How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
Where on the periodic table is the element found?
Please describe the element you are looking for.
What element is used to paint your skin to prevent cuts from infecting?
The element you're looking for is... Iodine.
What element has two 2s electrons?
Actually the atomic number tells you how many protons there are. And there are 6 elements with 2 electrons. You can find out that out by looking at a periodic table and looking at family 2. Im guessing you won't be able to find the element your looking for unless you know the number of nuetrons or even better the number of protons.

Is it always possible to identify something as an element compound. Substance or mixture just by looking at it?
Very rarely is possible; generally to identify an element or compound it is absolutely necessary to realize a deep chemical/physical analysis.
Is it possible to identify something as an element compound pure substance or mixture just by looking at it?
Very rarely is possible; generally to identify an element or compound it is absolutely necessary to realize a deep chemical/physical analysis.

How can you predicted the absorption spectrum of a solution by looking at it's color?
By looking at its emission spectrum and seing where the black lines are
How are spectrums used to study?
Astronomers use the light spectrum of distant objects to determine the chemical composition of those objects. Each element on the period table gives off a different spectrum, and by looking through a spectrometer an astronomer can read the spectrum and figure out what that object is made up of to gain better understanding of our universe.
What spectum is obtained When any element in the gas phase is excited to the point where it emits visible light?
When any element is excited to the point where it emits visible light, it emits a unique spectrum. The mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.
