how reactive is radon and will it combine with other elements
Noble gases do not often combine with other elements.
nnnn
Other elements that would have properties similar to radon include other noble gases such as helium, neon, argon, krypton, and xenon. These elements are all inert and have low reactivity due to their stable electron configurations. Like radon, they are all colorless, odorless, and tasteless gases at room temperature.
Today only helium is known as a chemical element without stable compounds. Elements that do do combine with other elements are called "inert" or "noble", Gold is an example of a noble metal, platinum is another. Group 18 gases, like helium, neon, argon, krypton, xenon, radon are noble gases. They were considered noble because they did not easily form compounds. Chemistry has advanced since the 1960's and that is no longer the case.

The Inert Gases of Group 0 rarely combine with other elements as they are (exc. Radon) extremely unreactive. The Inert Gases are:HeliumNeonArgonKryptonXenon(Radon)
The Group 0 - Inert Gases group are all (exc. Radon) highly unreactive, and so don't chemcially combine with other elements.
Noble gases do not often combine with other elements.
There are no elements in Radon, Radon is an element in its own right.
no
They can combine in lots of ways. Some reactive elements will combine on their own but others need heating to combine. Noble gases (krypton, argon, xenon, helium, neon and radon) do not react (combine) with other atoms.

Uranium combine with the majority of other elements; also uranium has alloys with the majority of metals.
For example halogens, carbon, oxygen, sulfur, other nonmetals.
