Arjuna Posted December 13, 2004 Report Share Posted December 13, 2004 (edited) Here is a direct quote from http://www.webelements.com/webelements/ele...xt/Uup/key.html. Considering how important Elerium is to X-COM, I thought this fitting. "Ununpentium 115Uup[288] The essentialsName: ununpentium Symbol: Uup Atomic number: 115 Atomic weight: [ 288 ] CAS Registry ID: 54085-64-2 Group number: 15 Group name: Pnictogen Period number: 7 Block: p-block Description Here is a brief description of ununpentium. Standard state: presumably a solid at 298 K Colour: unknown, but probably metallic and silvery white or grey in appearance Classification: Metallic Availability: Not commercially available. Experiments resulting in the formation of element 115 were reported in February 2004 following experiments carried out between 14 July - 10 August 2003 involving scientists at Dubna (Joint Institute for Nuclear Research at the U400 cyclotron with the Dubna gas-filled recoil separator, DGFRS) in Russia in a collaboration also involving scientists at the Lawrence Livermore National Laboratory, USA. Only four nuclei were identified and the claim has not yet been ratified, but the results are now published in a reputable peer-reviewed journal. IsolationHere is a brief summary of the isolation of ununpentium. Currently, the identification of element 115 is yet to be confirmed by IUPAC, but the experiments leading to element 115 are now published in a prestigious peer reviewed journal. As only about four atoms of element 115 have ever been made (through nuclear reactions involving fusing calcium nuclei with americium nuclei) isolation of an observable quantity has never been achieved, and may well never be. 24395Am + 4820Ca > 287115Uup + 4 1n 24395Am + 4820Ca > 288115Uup + 3 1n In these first experiments, three nuclei of the 288Uup isotope were made and one of the 287Uup isotope. All the nuclei formed decayed in less than a second by emitting a-particles. These decays resulted in isotopes of element 113 (mass number 283 or 284, containing 113 protons and either 170 or 171 neutrons). These isotopes of element 113 are also radioactive and underwent further a-decay processes to isotopes of element 111 and so on down to at least element 105 (dubnium). 287115Uup > 283113Uut + 42He (46.6 milliseconds) 288115Uup > 284113Uut + 42He (80.3 milliseconds) 288115Uup > 284113Uut + 42He (18.6 milliseconds) 288115Uup 284113Uut + 42He (280 milliseconds)" Hopefully Xenocide doesn't plan on using element 115. EDIT: Added the arrows, they didn't show up when I copied it. Edited December 13, 2004 by Arjuna Link to comment Share on other sites More sharing options...
Guest Azrael Posted December 13, 2004 Report Share Posted December 13, 2004 Nope, ours is number 122 Link to comment Share on other sites More sharing options...
[Blehm 98] Posted December 18, 2004 Report Share Posted December 18, 2004 Element number 115 was a recently made atom created by partically accelerating atoms together, which created number 115, which only existed for less than a second Link to comment Share on other sites More sharing options...
Denevive Posted December 31, 2004 Report Share Posted December 31, 2004 And the 122 has nothing to do with an atomic number. Link to comment Share on other sites More sharing options...
Guest Azrael Posted December 31, 2004 Report Share Posted December 31, 2004 You are right, since I got here I always thought it had to do with the atomic number. Link to comment Share on other sites More sharing options...
Judge_Deadd Posted December 31, 2004 Report Share Posted December 31, 2004 And the 122 has nothing to do with an atomic number.<{POST_SNAPBACK}>So, what it is about? I was sure that 122 was atomic nr, too... Link to comment Share on other sites More sharing options...
mikker Posted December 31, 2004 Report Share Posted December 31, 2004 i though it was too? Link to comment Share on other sites More sharing options...
Brick-To-Face Posted June 25, 2005 Report Share Posted June 25, 2005 Since they explain that E115 has properties of antimatter, wouldn't it make wore sense to say that aliens have stockpiled antimatter (stored in antimatter rods). The power source could simply be a thermal reactor that uses the magnetic properties of alien alloys to pump antimatter into a reaction chamber (similar to that of a common nuclear reactor) but this type of reaction would be much more controlled. And there's no need for bulky control rods. Link to comment Share on other sites More sharing options...

Steelion Posted June 29, 2007 Report Share Posted June 29, 2007 Wait- 115/122 doesn't refer to atomic number? Link to comment Share on other sites More sharing options...
Guest Azrael Posted June 29, 2007 Report Share Posted June 29, 2007 a very nice topic...Cut the spamming/thread necromancy, either post content or don't post at all. Wait- 115/122 doesn't refer to atomic number?115 did, IIRC.122 refers to the number of experiments it took the X-Corps scientists to figure out what it was (something along those lines).

Steelion Posted June 29, 2007 Report Share Posted June 29, 2007 Ah. That makes sense. Sort of... Link to comment Share on other sites More sharing options...
