synthetic isotopes[edit]

Don't the readers have a right to know whether the isotope is synthetic or not? Starhood` 21:37, 1 October 2006 (UTC)

chemical and "normal" physical properties[edit]

shouldn't there also be a section in which the "regular" physical and chemical properties are outlined (boiling point, melting point etc. etc) 194.53.253.51 (talk) 09:06, 9 November 2009 (UTC)

Yes, and comes the question that, since radon is an inert gas, how do you know that there is any of it except for its radioactivity? And the second question, is there a procedure that permits us to say categorically that there are no stable isotopes of 86Rn Radon?WFPM (talk) 13:09, 8 May 2011 (UTC)

Representative Isotopic Composition / Mole Fraction[edit]

222Rn is listed as "trace" in the table.

Shouldn't it be listed as > 99% (or > 0.99)? I.E. it may occur as trace quantities in nature, but most of what is found is 222Rn. Sorry, I don't have the specific percentage. Keelec (talk) 17:49, 5 May 2013 (UTC)
