aman Posted December 20, 2003 Share Posted December 20, 2003 When we start building the elements 120 and above on the periodic table, do you expect some will be super strong, radiation resistant, maybe super conductive or super insulators? The problems we face now with space travel vulnearablilities may someday be eliminated if we have new materials better than what we have now. Do any of the elements exist naturally in the universe?

aman Posted December 22, 2003 Author Share Posted December 22, 2003 The Cyclotron at Berkley aims high energy Krypton ions at Lead to make the elements up to 118. Our Milky Way Galaxy has ripped apart a couple smaller galaxies and they pass through our galaxy obliquely so there should be potential for some incredible collisions. If two Neutron stars collided at high speed, wouldn't there be potential for a lot of heavy elements thrown into space? Just aman Link to comment Share on other sites More sharing options...
NSX Posted December 23, 2003 Share Posted December 23, 2003 Well, all I know is that as the elements become heavier, they become more unstable; so I'm not sure if they're viable for reality. Link to comment Share on other sites More sharing options...
wolfson Posted December 23, 2003 Share Posted December 23, 2003 I think when you have found super heavy elements then in the future the " Island of Stability" will have been found and only then can we theorize the wonders of Nucleosynthesis.

YT2095 Posted December 24, 2003 Share Posted December 24, 2003 elements from atomic weight 84 (Xe 6P4) and above are considered unstable as a genral rule of thumb, although elements such as Cerium do have stable isotopes (it`s used as an alloy in lighter flints) and the nitrates of it impregnated into cotton are used as a replacement for the slightly radioctive Thorium used in old Gas Mantles Link to comment Share on other sites More sharing options...
aman Posted December 24, 2003 Author Share Posted December 24, 2003 Bi Z83/i209 isotope is the last stable element I can find. http://ie.lbl.gov/education/isotopes.htm Still on these isotopes there are a dozen or so for each heavy element. By chance one out of the two isotopes so far created of 114 lasted about 30 seconds before decay. That gives me hope one of the other isotopes might be stable.
