Element 114 Verified 142

ExRex writes "A team at Lawrence Berkeley National Laboratory has observed the production of superheavy element 114, confirming the results of researchers at the Joint Institute for Nuclear Research in Dubna, Russia. Those researchers first reported producing element 114 in 1999. Such independent verification is important, particularly given the evidence of fabricated results for other superheavy elements.

      There's an interesting caveat to calling this element heavy. Just because it has 114 protons doesn't necessarily mean that it's "heavy". The "heaviest" elements are the densest ones, which tend to fall in the middle of the transition metals. If I recall correctly, 114 falls on the on the right side of the transition metals, so it might not be all that "heavy". There are reasons why this happen, something about the f-orbitals actually allowing atoms to get closer to one another, but it's been a long time

      A variety of reasons. First of all, because it is interesting and fun. Why do you think people are searching for very large prime numbers? http://science.slashdot.org/story/09/10/15/154227/12M-Digit-Prime-Number-Sets-Record-Nets-100000 [slashdot.org] Do you think they are all doing this because of possible benefits to abstract areas of number theory any more than people climb Everest for practical reasons? Second, seeing that these elements match up to our predictions help us get a better understanding of physics. Third, there is some reason to suspect that there may be farther ahead islands of stability where the elements become more stable again. While it is unlikely that those areas are stable enough for those elements to live long enough to be of practical use, the chance otherwise is not tiny. So there may be direct practical benefits. But the main reasons are because it is cool and humans are ever curious creatures.

        Those "islands of stability" have been predicted long time ago. What I don't understand is why those researchers do not try to make those elements, instead of the intermediate ones.

        Afaik making those superheavy elements is done by fusing lighter ones. Not by building them up brick-by-brick (or proton/neutron by proton/neutron). So I wonder why not just go for the ones that are predicted to be more stable? Is there something we need to know from slightly-less-heavy elements that we can't predict before maki

          Well it's not like they're purposely missing the target here... They've tried to make isotopes with a higher n/p ratio near the island of stability it's just that it's hard to find two high n/p isotopes to smash together to make a larger one. As you go toward higher elements the n/p ratio needs to be larger to afford more stable isotopes. This means that you'd effectively need to smash two isotopes together that have n/p ratios ideal for higher elements but markedly unstable for lower elements. THen there's the problem that when you smash two isotopes together to make these higher elements, it often knocks out a few neutrons from the composite nucleus due to the sheer high energies involved. This means that you'd probably have to use lower isotopes that have even higher n/p ratios that just don't last very long. (they're very unstable) Of course you'd think that you could just keep adding neutrons or tritium nuclei repeatedly to get higher elements but that doesn't work either as it usually ends up causing a fission reaction. In fact, the vast majority of any reactions attempted so far to produce higher elements has resulted in an inordinate number of composite nuclei undergoing fission immediately. Out of 10^12 reactions, you'd be fairly lucky to find one of them actually producing an isotope of a higher element.

        • What I don't understand is why those researchers do not try to make those elements, instead of the intermediate ones.

      Well, the closer we can get to finding an island of stability [wikipedia.org], the better.
      • So why don't we see those stable elements in nature?

        • Just because we don't find them in earth-bound surface-accessible "nature" doesn't mean they don't exist somewhere in the universe - perhaps somewhere out there was a heavier supernova that produced element 114 or higher.

          They would only be produced in supernova and in vanishingly small quantities. This isn't as unreasonable as it sounds. We've had cases of elements discovered first in stars and then on Earth (helium) but we've also had the reverse where an element has been discovered on Earth and after having a better idea what we are looking for we find it in stars. However, even if these more stable elements exist they would not be at all common. Supernova aren't very efficient producers of heavy elements. They have trouble producing elements much past uranium because stars can't get so big and they aren't deliberately smashing things together repeatedly.
        • by wvmarle (1070040)

          Predicted half-lives are in the order of hours, maybe days. That's why. That's also why many of the lighter elements we can make artificially are not (or barely) present in nature. Think of all the elements used in radiotherapy and so, they also tend to have half-lives in the order of hours or days.

          Perhaps the same reason we don't see astronomically common stable elements like Tellerium.

          From http://en.wikipedia.org/wiki/Tellurium [wikipedia.org]:

          The extreme rarity of tellurium in the Earth's crust is not a reflection of its cosmic abundance, which is in fact greater than that of rubidium, even though rubidium is ten thousand times more abundant in the Earth's crust. The extraordinarily low abundance of tellurium on Earth is because during the Earth's formation, the stable form of elements in the absence of oxygen and water was controlled by the oxidation and reduction of hydrogen. Under this scenario elements such as tellurium which form volatile hydrides were severely depleted during the formation of the Earth's crust through evaporation. Tellurium and selenium are the heavy elements mostly depleted in the Earth's crust by this process.

          Why don't we see Plutonium or Neptunium in nature? Because despite there being "stable" isotopes with half-lives measured in millions of years, the age of the Earth is several orders of magnitude greater than that. Any isotope with a half-life less than about 30 million years would be completely decayed over the current age of the Earth (~4.5 billion years), even if it began as abundant as Iron (nearly 1/3 of Earth's mass) not a single atom would remain today.

      Most of the transuranic elements, are super unstable nucleii, that decay in second. According the nuclear shell theory, certain nucleii with magic numbers of either protons or neutron or both, would be extra stable, maybe stable enough to be a useful radioisotope. Proton numbers 110,114 and 126 are sure magic numbers. So finding element 114 should help confirm the theory, unfortunately its very hard to make such an element with enough neutrons, so the isotopes confirmed today are neutron short and only last a few second, 288 and 288 Uuq 114, better than the near by isotopes that only last milliseconds, but to short even to be chemically analysed. 298 Uuq 114, (ten neutrons more), is the on that is predicted to be to extra stable.

    An old Poul Anderson story, Mirkheim, used a stable superheavy element, eka-platinum, as a Maguffin.

    In the novel, the stuff was produced in a supernova. A gas giant planet was walloped by the explosion, blowing away its atmosphere leaving a creamy nougat center very dense rocky core. The heavy elements produced by the supernova were plastered across its surface.

    As I recall, the planet's discovery by the galaxy's great powers caused a political crisis and the threat of war. The stuff was highly valued. The one use I recall was a hull plating used by hydrogen-breathing races.

    I was pleased to read that Heino Nitsche is one of the project's lead researchers. His general chemistry course at Berkeley was very informative and enjoyable (and not just because he has a German accent and glorious mad scientist mustache [lbl.gov]); I've yet to meet someone who can get that excited about chemistry at 9 a.m. :)

    I still remember a story he told us during the unit on radioactivity and nuclear decay. One of his cats, sick with cancer, was treated with radioactive I-131. After the cat "cooled off" at the vet hospital, Heino took him home, nursed him back to health, and, like a true scientist, measured the cat's radioactivity every morning with a Geiger counter. Sure enough, the measured decay curve strongly matched the predicted one. The cat lived for several more years, too.
