Element 115 Ununpentium

Postby RQ » Mon Feb 16, 2004 8:39 am

I found some information in a long-closed site "abovetopsecret.com"
It has some information on element 115 and 118:

Density @ 293K: 31.5g/cm^3 Atomic Volume: 13.45 cm^3/mol
Group: Superheavy Elements Discovered: 1989
State: Solid Melting Point" 1740C Boiling Point:3530C
1st Ionization Energy: 531 kJ/mol
2nd Ionization Energy: 1756 kJ/mol
3rd Ionization Energy: 2653 kJ/mol
Heat Atomization: kJ/mol atoms (don't know what it means here)
structure: FCC face-centered cubic
color: Reddish-orange
Uses: Reactor Fuel (This whole thing suggested that it powered alien craft)
Characteristics: Stable (Don't quote me here)
Thermal Conductivity: 6.1 J/m-sec degrees
Polarizability: 20.5 A^3
Electrical Conductivity: 7.09 1/mohm-cm
Everything else is uknown

Also: New Superheavy elements created:

->Kr-68 + Pb-208 -> Fusion -> Compound Nucleus(extract a neutron) -> Element 118. This might be of some interest to Polyhedron Dude.

For further info say something. It says that 118 having 118 protons and 175 neutrons decays to an isotope of element 116 with 116 protons and 173 neutrons and it takes it less than a thousandth of a second to decay to it by emitting an alpha particle. This further alpha-decays to an isotope of 114. (should be beta thought)

This info from the web site seems a bit faked, element 115 which would be under bismuth on the periodic table would likely have a melting point in the 300C to 500C vacinity, and would have a density closer to 14g/cm^3. The above properties would be more fitting for element 110 - darmstadtium which is under platinum. Talk about elements, I'm expecting my first europium sample to come in the mail soon :D .

Helas, you can wait on that forever, the higher elements one systematized the name calling based on some numbersystem.
Ununpentium already says 115
So europium won't be comming into your mail, it simply doesn't fit.
(or it must be some nickname)

Europium so is not fitting to denote an element, it could be some structure celebrating the unification of europe or something like that.

Europium is one of the rare earth metals (element 63) - it is even sold on Ebay.
