Radon is also oxidised by dioxygen difluoride to RnF 2 at 173 K (−100 °C; −148 °F). [25] Radon oxides are among the few other reported compounds of radon; [29] only the trioxide (RnO 3) has been confirmed. [30] The higher fluorides RnF 4 and RnF 6 have been claimed [30] and are calculated to be stable, [31] but their identification is ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

In chemistry, noble gas compounds are chemical compounds that include an element from the noble gases, group 8 or 18 of the periodic table.Although the noble gases are generally unreactive elements, many such compounds have been observed, particularly involving the element xenon.
When this number is >118, the template expands with periods 8 and above, adding the (predicted) elements with atomic number >119. Apart from this 118/119 switching, the parameter is not used as an atomic number. {{Periodic table (32 columns, micro) | number = 119}}
Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2
