Learning to Recognize Element Spectra


I have opted not to include the transuranium elements, nor unstable short lived elements like polonium or radon, nor any element I have not photographed and never could photograph. It is very unlikely that you would encounter any of these, and most of them do not have their entire spectrum known, but only several bright lines. (In the case of astatine, no visible lines are known at all!) So not only are these elements that very few people would ever have to identify, and definitely not in a place without expensive laboratory equipment such as a spectroscope with sub-Ångström accuracy - but also, any attempt at a visual description would likely fall so far short of reality as to be unusable anyway.
