Open reserve Paper Chemistry Open maintain Paper Atomic spectroscopy is a chemical analysis technique and it is used to identify what elements are in a compound. It uses the idea of a photon being absorbed or emitted whenever an negatron changes from one zipper level to another. The diagram be first shows sodium table salt being sprinkled onto a flame and yellow-bellied vindicated being emitted. Emission spectra are produced by change state gases in which the atoms do not experience many collisions (because of the low density).

The emanation of yellow light occ urs because the electrons of the sodium salt call down been promoted to a higher electronic energy state only have then fallen back down and emitted the energy as an electromagnetic wave, in the wavelength corresponding to yellow which is ? 600 nm. The much exquisite that the yellow band is the more abundant the sodium salt present. The diagram (left) shows an atomic excitation caused by the assiduousness of a photon and an atomic de-exc...If you want to get a teeming essay, orderliness it on our website: OrderCustomPaper.com
