Notes

Note that elements 113, 115, and 117 are not known, but are included in the table to show their expected positions. There are unconfirmed reports for the observation of elements 114 (ununquadium), 116 (ununhexium), and 118 (ununoctium) and so these elements are also included. Note that the reports for 118 have been retracted.
