Just as chemists arranged elements in the periodic table by their atomic weight and group to 4 new insights, the researchers hope that organizing these atomic shapes by their various 5 will help in understanding them. The team has assigned each atomic shape a sequence of numbers 6 its features...

The biennial review of determinations, (E), and other cognate data has warranted no changes for the of the elements from that previously published in the Table of Atomic Weights 1995 with the exception of a new footnote for lithium. The names for the transfermium elements with atomic numbers ...
Results are tabulated for atomic numbers Z = 6–87 for the K shell and Z = 12–92 for the L subshells. These matrix elements can be used to calculate approximate Auger rates in multiply ionized atoms; the matrix elements are expected to be very useful for the computation of Auger rates...
