Question

list of 10-10 uses of radon and oganesson gasses

Answer 1

Radon gas is a colorless, odorless gas that most people associate with the risk of lung cancer. It does have its uses, though they are limited
Oganesson's most stable isotope, oganesson-294, has a half-life of about 0.89 milliseconds. It decays into livermorium-290 through alpha decay. Since only a few atoms of oganesson have ever been produced, it currently has no uses outside of basic scientific research.
