Radon is an element of group 18. This is the group of the noble gases.
Radon is an inert gas. The so-called noble gases are in column 18 of the Periodic Table, and radon is at the bottom.
Xenon and radon are noble gases. They belong to noble gas family or group 18 on the periodic table.
alkali earth metals
Helium, neon, argon, krypton, xenon and radon all belong to group 18.
Noble gases belong to group 0 and can be found on the extreme right column of the periodic table of elements. The heaviest noble gas would be radon, whose atomic mass is still uncertain. The element which appears below radon in the column, ununoctium, has not been confirmed as a noble gas.
element 17 (Cl) chlorine belongs to the hologen group. It is a gas.
