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 ...

Radon compounds are chemical compounds formed by the element radon (Rn). Radon is a noble gas, i.e. a zero-valence element, and is chemically not very reactive. The 3.8-day half-life of radon-222 makes it useful in physical sciences as a natural tracer. Because radon is a gas under normal circumstances, and its decay-chain parents are not, it ...

Group 12, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd), mercury (Hg), [ 2 ] [ 3 ] [ 4 ] and copernicium (Cn). [ 5 ] Formerly this group was named IIB (pronounced as "group two B", as the "II" is a Roman numeral ) by CAS and old IUPAC system.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
