Radon is formed from the decay of which element?

Explanation:
Radon comes from the uranium decay series. In the uranium-238 chain, uranium-238 decays through a series of steps to radium-226, which then decays to radon-222. So radon originates in the uranium decay process, not from thorium, plutonium, or bismuth.
