The emission spectrum of an element acts as a fingerprint for identifying the element. . Electrons exist in energy levels within an atom. These levels have well defined energies and electrons moving between them must absorb or emit energy equal to the difference between them. When an atom is ...
The X-ray emission spectrum was analyzed and the results showed that comet C/1999 S4 (LINEAR) from the Oort cloud region (long-period) and comet 9p/Tempel 1 from the Kuiper Belt region (short-period) had the highest abundances of the different elements. The ds9...

The emission spectrum characteristics of some elements are plainly visible to the naked eye when these elements are heated. For example, when platinum wire is dipped into a strontium nitrate solution and then inserted into a flame, the strontium atoms emit a red color. Similarly, when copper is...

CONSTITUTION:The emission of spark electrode L is made into a bright line spectrum by a dispersion element G and appears on surface S. The bright line spectrum of the element to be determined is received by a photoelectric multiplier P1, and plural bright line spectra of substrate elements are...
