Links to radii data
Data for each element are divided into categories, each of which is further divided into subcategories. The categories and their subcategories are listed in the menu panel to the left. Select from that menu to display a periodic table with links to your chosen data.
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 Note that the reports for 118 have been retracted.
