andy Posted February 12, 2004 Share Posted February 12, 2004 Is it true that this month there were claims that somebody had discovered/created Ununtrium(element 113) and Ununpentium(element 115)? Were elements like Unununium renamed? Link to comment Share on other sites More sharing options...
greg1917 Posted February 12, 2004 Share Posted February 12, 2004 Once the results are shown to be repeatable in other labs, the discovery will be verified and adopted in academia. Those names may or may not be used when (or indeed if) the findings are verified. Unununium, element 111, has not been renamed, why would it be?

andy Posted February 12, 2004 Author Share Posted February 12, 2004 Because other elements that were named like it were renamed. Rutherfordium was Unq (Unnilquadium). Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted February 12, 2004 Share Posted February 12, 2004 My favorite element is Unobtanium. Just kidding. Are these elements ones that exist for a tiny part of a second? Link to comment Share on other sites More sharing options...
aommaster Posted February 13, 2004 Share Posted February 13, 2004 yeah they are actually speaking. They can't exist for long because their nuclie break down because it is so big Link to comment Share on other sites More sharing options...
JaKiri Posted February 13, 2004 Share Posted February 13, 2004 There's a theoretical island of stability around 140, if memory serves. Link to comment Share on other sites More sharing options...
agaubr Posted February 16, 2004 Share Posted February 16, 2004 Yes A calcium adn americuium nuleci were collided to yield the 115 element and 113 element on decay. The yield was given as 4 atoms of 113 and these lasted only miliseconds. Ag Link to comment Share on other sites More sharing options...
aommaster Posted February 16, 2004 Share Posted February 16, 2004 its sad that these elements only last for less than a second! ...sigh... Link to comment Share on other sites More sharing options...
Dudde Posted February 17, 2004 Share Posted February 17, 2004 stable or not, at least chemistry is getting somewhere Link to comment Share on other sites More sharing options...
aommaster Posted February 18, 2004 Share Posted February 18, 2004 yeah i agree! By the end of 2400, we may have 500 elements!!! LEARN THEM ALL WITH THE SYMBOLS!!! Yikes! Link to comment Share on other sites More sharing options...

NSX Posted February 21, 2004 Share Posted February 21, 2004 lol I remember from The Simpsons: Lisa: "*gasp* Their periodic table has 250 elements!" Link to comment Share on other sites More sharing options...
5614 Posted August 3, 2004 Share Posted August 3, 2004 chemists are always creating new elements, by bombarding existing elements with either: other elements or neutrons, [sometimes; electrons, protons] in the end the original atom joins or merges with whatever is being "thrown" at it,,, ta daaa, new element, but its soooo unstable, it quickly decays, normally through radiation! and it only lasts for a few seconds, but it was there all the same! lol, how pointless! still, its done!! but they havent succeded in making a new & stable particle yet! these are done in particle accelerators, check it out on google, im sure there will be something there!

SurfSciGuy Posted August 3, 2004 Share Posted August 3, 2004 Current publications on nomenclature can be found at the IUPAC website: http://www.iupac.org/general/FAQs/elements.html#pt I think Seaborg predicted an island of stability below Lead (think that's about 140 or something). There have been quite a few controversies concerning the naming of the elements 101 upwards some of them have been renamed several times. Link to comment Share on other sites More sharing options...
