Open reserve Paper Chemistry Open watchword Paper Atomic spectroscopy is a chemical analytic flimsyking 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 dynamism level to another. The diagram be paltry shows atomic number 11 table salt being sprinkled onto a flame and discolor vindicated being emitted. Emission spectra are produced by thin gases in which the atoms do not experience many collisions (because of the low density).

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