Radon is a noble gas and is radioactive.
Radon is the radioactive noble gas.
Nothing abnormal; radon is also a noble gas and radioactive.
Radon is a noble gas and is radioactive. All of the other noble gasses have at least some synthetic radioactive isotopes. Radioactive isotopes of both krypton and argon exist in nature in trace quantities.
Radon (Rn) as it is radioactive.
1. Any hazard, but noble gases are not respirable. 2. Radon is very radioactive and dangerous.

There is no such thing. There is radon gas, which is a radioactive noble gas. It is given off by some rocks and soil.
Neither. Argon is naturally occurring noble gas
Uranium is a not a noble gas, but a metal, solid, radioactive, member of the actinides (actinoids) family.
Radon is a very radioactive and dangerous gas.
Radon is a radioactive gas and one of the noble gases. Dangerous.
Ununoctium is an artificial radioactive element, first time prepared in 2006.
