The energy levels of an atom are the distinctive property of that atom. The difference in energy levels determine the amount of light that could be emitted or absorbed. There is no same energy level difference from one atom to another, therefore spectral lines are referred to as an "atom's fingerprint". The spectral lines make atoms unique, just as fingerprints make people unique, no two humans have the same fingerprints.
each atom radiates light according its electronic configuration and as atoms have varying numbers of electrons and they occupy different energy states any spectra obtaining would reflect this
Fingerprints are a visual pattern used to identify a person, and spectral lines are a visual pattern used to identify an element. So the similarity is clear.
because it is dude! get a life!
Intensity of spectral line show the abundance of different elements in the light source. Every element has its own "fingerprint" which can indicate its presence.
It merely means that the amount of this element in the visible part of a star - the part that emits the spectrum - is too small to be detected by this method.
Helium
have different sets of spectral lines. :) u got to love astronomy
spectral analysis of light of stars help us
Each element has an unique set of attributes, just like fingerprints. One of the most common attributes of elements used is its spectral signature. When an element is excited, it emits photons on specific frequencies. These frequencies can then be used to map things such as the chemical composition of distant exo-planet atmospheres or moons, such as Titan.
An atomic fingerprint is a unique set of lines that identifies each element. The lines act much as DNA in a human, they are exclusive to the particular element, and caused by the energy level of the element.
The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
Oxygen is the element produced after photosynthesis.
Elements have several spectral lines and although some lines may be the same between different elements most lines are not and the whole spectrum for each element is indeed unique.
What makes up the star or element.
That's because it can be used to clearly identify an element; just as fingerprints can be used to identify a person.
Each spectra is unique to each element as fingerprints are to humans because they each have their own spectral pattern and by comparing the spectra of a known element to the unknown element or ion you can identify them.
It sort of depends on what you mean by "discovered". It was known in the late 1800s that certain mineral samples produced spectral lines that could not be accounted for by any known element. However, Europium was first isolated in 1901 by Demarcay.
