The Real Elerium-115

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 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.

Nope, ours is number 122

[[Blehm 98]]

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

[Denevive]

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

[Guest Azrael]

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

[Judge_Deadd]

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...

[mikker]

i though it was too?

[Brick-To-Face]

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.

[Adun_Toridas]

a very nice topic...

[Steelion]

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

[Guest Azrael]

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]

Ah. That makes sense. Sort of...
