Here is a direct quote from http://www.webelemen...xt/Uup/key.html.

Considering how important Elerium is to X-COM, I thought this fitting.


"Ununpentium 115
Uup
[288]

The essentials
Name: 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.

Isolation
Here 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.

Nope, ours is number 122

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

And the 122 has nothing to do with an atomic number.

You are right, since I got here I always thought it had to do with the atomic number.

<{POST_SNAPBACK}>

So, what it is about? I was sure that 122 was atomic nr, too...

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.

Wait- 115/122 doesn't refer to atomic number?

Cut the spamming/thread necromancy, either post content or don't post at all.

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).

Ah. That makes sense. Sort of...
