Long-lived Super Heavy Element Created 110
treeves writes "Radioactive nuclei that hang around for a mere half-minute before falling apart hardly seem stable. Yet compared with the fleeting lifetimes of their superheavy atomic neighbors, the roughly 30-second period that transpired from creation to disintegration of four atoms of a newly discovered isotope of element 108 qualifies those atoms as rock solid.
Theoretical physicists predicted years ago that some nuclei of elements much more massive than uranium should survive for a relatively long time — possibly long enough to probe their chemical properties — if they could be synthesized. On the chart of nuclides, theoreticians pinpointed a region with coordinates corresponding to 114 protons and 184 neutrons and indicated that nuclei with those "magic" numbers of subatomic particles should lie at the center of an island of stability. The nuclear longevity, according to the models, is due to the closing of proton and neutron shells, which renders the particles stable against spontaneous fission much the same way that a filled outer electron shell endows noble gases with chemical inertness. Experimentalists, though, haven't yet found a route to reach the center of the island."

True. However 114 isn't really stable... the superactinde branch is supposed to represent heavy elements that are predicted to be stable on the order of years, or the red peak of the island (even if it looks like the two diagram don't align up right). Good observation though, and honestly I'm not 100% confident about this topic; I only have a BS in chem.

Have you got any references? Most stuff I've seen seems to consider ununquadium-298 (Z=114, N=184) the most likey candidate for stability. See, for example, this pbs segment [pbs.org], or this [nature.com]. Though I know 126 is considered to be a magic number so Z=126, N=184 should also be very stable.

The problem, as I understand it from following the news of the quest for heavy elements, is that these are very likely to not be created in a nova or supernova because of the incredibly tricky order of nuclear reactions required. The short half-lives of the intermediate elements are such that there is no time to build them up to the required size. If it decays faster than the arrival of more stuff, you'll never get there.

I'm not a physicist, and barely remember the difference between protons and neutrons. Really. Probably it's the way they choose the names, having nothing to do with the physical properties of the elements, and not even sounding cool. I mean, Uranium, Plutonium, Titanium have cool names. Krypton -- cool name. "Carbon" is at least descriptive, deriving from the Latin for burning. I've always thought "Gold", "Iron", and "Lead" were onomatopoeic. And everyone knows that "Sodium" is Greek for "soda pop". Good names, all, and they don't sound phake and made up.
But "Hassium"? "Bohrium"? Not cool, not descriptive. These are vanity names, like getting your name in a phony star registry, or some weak license plate, except it goes in the encyclopedia. Yes, I know there's this tradition for naming the radioactive ones after people, but that kind of thing ought to be left to the entomologists [uwyo.edu], hadn't it?

Up to the iron group, fusion reactions are exothermic but produce increasingly less energy, so the higher the mass of the resulting element, the more reactions are needed to produce the energy required to sustain a star.
Reactions beyond the iron group are endothermic so require energy from the star to complete.
The other way elements are produced in stars is the addition of neutrons to already existing atoms, hence increasing their atomic mass and producing a different element. IIRC, the energy required to do this is high and exists only in stars.
There are two types of this reacton, slow and fast. Slow happens in the normal course of events of star evolution where fast happens in the seconds of life during and after a supernova. Elements such as uranium are produced during the fast process. From this, I think these guys have replicated one of the slow/fast addition processes rather than what we tend to call fusion.
As I say, IANAP but that's what I remember.
