   Yes, that why I did not question the first """is""".   
      
   And, again, if radon is an incorrect answer in 2022, it was an incorrect   
   answer in 2012 as well, but the correct answer in 2012 would be "element   
   118", as it had not yet been named.   
      
   Then again, it's only on the days when they produce some oganesson atoms,   
   radon is not the heaviest noble gas...
