Can both Rutherford and Bohrs model of the atom explain spectra lines of elements?
Bohr model explain these spectra.
Who studied the x-ray spectra of the elements to reveal the ir periodicity?
mosely
What is the name of the spectrum when elements produce different colors when heated?
Atomic spectra
How can you identify a unknown compound using uv spectroscopy?
Each compound has a specific absorption spectra.
How an elements particular emission or absorption spectra would be important to geologist astronomers and chemists?
geologists would be aided by these spectra in searching underground with different wavelenths and then determine the elements in the surrounding earth or soil An astronomer would be able to penetrate dust clouds and space debris to look at the fundamental compositions of a star or stellar system. These spectra tell you what elements are in something that you cannot physically test/experiment with/melt.
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
Why are emission spectra called the fingerprints of the elements?
Because an emission spectrum is specific to an element.It can be used to identify the element
Why do scientists believe that stars contain the same elements as the solar system?
The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.
When a metal is heated in a flame the flame has a distinctive color the information was eventually extended to the study of stars because?
Because the color spectra of stars indicate which elements are present.
Can both Rutherford and Bohrs model of the atom explain spectra lines of elements?
Bohr model explain these spectra.
How is a star simmular to the Sun if it has the same absorption lines in its spectrum that occur in the Sun's spectrum?
because they will have the same elements in the atmosphere...
What can you now say about the spectra from various light sources?
The light source will give a spectrum that shows what elements are present. Each element will give of a particular colour, almost like a fingerprint.
Are swarovski elements genuine swarovski crystals?
They sure are! In fact, Swarovski Elements is the VERY BEST of the Swarovski Brand of crystals. Swarovski Elements was originally known as Swarovsk Strass. The more economical option is Swarovski Spectra. Anyway, LOOK FOR THE SWAROVSKI ELEMENTS LOGO, as it should be ENGRAVED on their chandelier crystals. Just looking at a chandelier in Spectra and another in Elements, and you will see immediately that Elements is far superior, but it is very expensive as well, hence the Spectra line.
Suppose you want to know the chemical composition of a distant star Which piece of information is most useful to you?
A telescope, whose light output would be sent through a spectral analysis machine of some type. That analysis of the emission spectra of the star would be compared to the known spectra of the elements to find the composition of the star.
What effect does the nucleus have on atomic spectra of different elements?
Aside from determining how many electrons the atom has, the nucleus does not affect the spectra of that atom in any way.
