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)
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)
Hello fellow Wikipedians,
I have just modified 2 external links on Isotopes of radon. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

215Rn (half-life = 2.3 µs) is the second least stable known nuclide with N:Z = 3:2, being second only to 5He. The next least stable is 275Ds (half-life = 62 µs).
Considering the short alpha half-life of 222Rn, I would be very astonished if they are not. 129.104.241.214 (talk) 02:56, 30 November 2023 (UTC)
Due to the extremely short alpha half-lives of nuclides in this region, beta decays have been so poorly studied for 212(m),213,214(m),216(m)At, 213,215,219,222Rn and 214(m),216(m),218(m)Fr. 2A04:CEC0:1088:EB77:D831:1EEE:AC25:2D1D (talk) 00:38, 14 May 2024 (UTC)
