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.
How can one identify functional groups in an IR spectrum?
Functional groups in an IR spectrum can be identified by looking for specific peaks or bands that correspond to characteristic vibrations of different functional groups. Each functional group has unique vibrational frequencies that can be matched to peaks in the spectrum, allowing for their identification.
Scientists can identify an element by looking at the structure of a single?
atom. Each element has a unique number of protons in its nucleus, which determines its atomic number. By analyzing the atomic number, scientists can determine the identity of an element.
How you can easily identify elements from compounds through its chemical formula?
You can identify elements in a compound by looking at the chemical formula and noting the symbols of the elements present. Each element is represented by a unique symbol (e.g. H for hydrogen, O for oxygen). You can determine the number of atoms of each element by the subscripts next to the element symbol in the formula.
How do you find out the atomic number of an element?
The atomic number of an element is equal to the number of protons in the nucleus of an atom of that element. You can identify the atomic number of an element by looking at its position on the periodic table - it is usually displayed above the element's symbol.
How is it possible to identify an element by looking at 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.
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.
What is platinum's emission spectra?
Its the light given off when you roast (of fry or even casserole) any element. Like in a light bulb glowing, not all the wavelengths of light are given off equally. By looking at what frequencies are there and which are missing you can tell which element you are looking at. You can tell what a distant star is made of using the same principle.

Can you identify a bush by looking at a photo of it?
Yes, it is possible to identify a bush by looking at a photo of it, especially if the photo shows distinctive features such as the shape of the leaves, flowers, or berries.
How can one identify functional groups in an IR spectrum?
Functional groups in an IR spectrum can be identified by looking for specific peaks or bands that correspond to characteristic vibrations of different functional groups. Each functional group has unique vibrational frequencies that can be matched to peaks in the spectrum, allowing for their identification.
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

Can a scientist identify a star's composition by looking at its continuous spectrum?
Yes, a scientist can identify a star's composition by analyzing its continuous spectrum. Different elements emit light at specific wavelengths, creating unique spectral lines that can reveal the presence of specific elements in a star's atmosphere. By analyzing these spectral lines, scientists can determine the composition of a star.
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.
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.
