There are no elements in Radon, Radon is an element in its own right.
how reactive is radon and will it combine with other elements
Most of them do. Radon probably does not.
Radon
actinium
I think it's RADON!!
Radon
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.
Radon has eight valence electrons. It's a noble gas, meaning that it does not react well with other elements.
These are the elements that are NATURALLY monatomic: Helium Neon Argon Krypton Xenon Radon
Radon is the heaviest of the inert gases. The inert gases are also known as the noble gases and are the lightest elements.
The Inert Gases of Group 0 rarely combine with other elements as they are (exc. Radon) extremely unreactive. The Inert Gases are:HeliumNeonArgonKryptonXenon(Radon)
