Notes:
Designations used in the ground shell lists:
[Ne] = 1s22s22p6
[Ar] = 1s22s22p63s23p6
[Kr] = 1s22s22p63s23p64s24p6
[Cd] = 1s22s22p63s23p64s24p64d105s2
[Xe] = 1s22s22p63s23p64s24p64d105s25p6
Uncertainty is given in parentheses after the value. It is expressed in the units of the last decimal place of the value.
