Re: Radon Found in my home! Ban Granite!
Under this topic of, "More fun with nuclear", I looked at the latest Periodic Table to-night. And I see physicists and chemists on the frontiers of science have been discovering some more elements, even beyond #106:
#107 Bohrium, #108 Hassium, #109 Meitnerium, #110 Damstadium, #111 Roentgerium, #112 Copernicium, #113 Ununtrium, #114 Flerovium, #115 Ununpentium, #116 Livermorium, #117 Ununseptium, #118 Ununoctium.
Part of the lower ( coming up from #106 down ) transition metal series, now to include #107 thru #112, inclusive.
Other (plain good old-fashioned) metals, include #113 thru #116, inclusive.
#117 is a halogen, and #118 is a noble gas. Thus, #117 Ununseptium is the highly reactive halogen, and #118 Ununoctium is the inert noble gas.
It's a safe bet to assume everything up here is radioactive (unstable). Everything up here fits the latest row across the Periodic Table. Everything down on this row ( up here in these atomic numbers ) would be excessively rare in the world. But who knows what exists on the Sun or elsewhere in this universe?
The important point, the take-home point, is that those isotopes of elements with the longest half-lives would be those elements that survive the longest in this world. Anything like Plutonium-242 with a 376,000 year half-life would last almost forever in this world because it is just about stable (and non-radioactive ). Plutonium-244 is even more stable with a half-life of 80 million years, so Pu-244 is not radioactive, no matter what the eco-frauds might say.... And the converse is also true: elements with extremely short half-lives, and some have half-lives of less than one-second, some even in micro-seconds, disappear almost instantly. So, virtually they don't exist in our world, except maybe in the Sun or in the stars.
Even I find a trip through the Periodic Table to be really cool, and I am just a lay-person on the street.
