Click on an element to get a listing of the contents in the Atomic Line List for that particular element (i.e., the number of levels and lines for each ionization stage). Some general data, such as name of the element and the recommended values for the average atomic weight and the standard isotopic composition are also included. Elements for which data are present in the Atomic Line List are marked in red.
NOTE: the precise structure of the 8th row is speculative. This is because the order in which the 8s, 7d, 6f, and 5g shells fill up as a function of the atomic number is not known.
