Why can the bright-line spectrum of an element be used to identify an element?
The wave lengths of lines of the spectrum are different for each chemical element.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
Which element did Bohr study the line emission spectrum of?
Niels Bohr studied the emission lines of Hydrogen.
What is the atomic emission spectra?
The colors of light given off when an element loses energy
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.
Why can the bright-line spectrum of an element be used to identify an element?
The wave lengths of lines of the spectrum are different for each chemical element.
Is it true that each element has a unique set of lines on a spectrum?
Yes , every element has different line in the spectrum.
How is the spectrum for an element similar to a person's fingerprint?
Each element has its own unique spectrum, just as each person has his/her own unique set of fingerprints.
Element named after brilliant indigo line in its spectrum?
Indium
What made William Crookes popular?
His most important discovery was that of the element thallium, which was previously unknown element with a bright green emission line in its spectrum. He also was the first person to discover helium.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
What element derived it name from the color of a spectrum line?
I suppose that you think to caesium (Cs).
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
Which element did Bohr study the line emission spectrum of?
Niels Bohr studied the emission lines of Hydrogen.
Why a spectrum of an element is called fingerprint?
That's because it can be used to clearly identify an element; just as fingerprints can be used to identify a person.
What are line spectra and why do they exist?
A spectrum that contains only certain colors, or wavelengths, is called a line spectrum. For every element, the emitted light contains only certain wavelentghs, giving each element a unique line spectrum. They exist for atomic fingerprinting, which is useful in identifying elements. They are also used in sodium-vapor lmaps, which are widely used for street lighting. They are also used in "neon" lights.
What is a line spectrum used for?
The line spectrum is usually used to sort out the atomic fingerprint as the gas emit light at very specific frequencies when exposed to the electromagnetic waves. The electromagnetic waves are usually displayed in form of the spectral lines.
