It's All About the Ununpentium 411

Posted by michael from the unobtainium dept.
spitefulcrow writes "The New York Times is reporting that elements 113 and 115 have been created by a joint team of Russian and American scientists. The temporary names are ununtrium and ununpentium until the experiment has been duplicated and verified in another lab. According to the article, speculation has been made that 'Rather than being round, nuclei in that region and beyond could contain bubbles and have strange doughnut-like shapes'."

    • In science a lot of times you do things just because you can. Maybe to check again your theory, hey, it might be wrong after all. So, this is a boundary, everyone thinks they know how it would be, but someone has to go there and make sure. It is just for the sense of discovery

I'm just wondering what they can do with the knowledge and theoretical stable atoms they develop.

      As other posters have said, the point is that we learn more about the nucleus - we find out exactly what the half-lives of these nuclei are, etc. This info could have applications to reactors, weapons, energy sources, etc. But the main point is that we know more about the universe. And one never knows where applications will come from. Sometimes a seemingly pointless discovery has a lot of real-world consequences - superconductors, for example, have revolutionized sensor technology for medical scanners and such (though we still don't have them for power lines). Other times, the big result is the spinoffs you come up with along the way - the internet was invented as a way to coordinate particle physics experiments.

      They create heavy elements, which are so unstable that they decay as quickly as they were created.

      So I'm wondering - what's the point ?

      Elements 83 (bismuth) and under have one or more stable isotopes, and one or more unstable isotopes. So, for example, hydrogen (element 1) is stable, but deuterium (H-2) and tritium (H-3) are not. Nevertheless, these unstable isotopes are useful. Deuterium is used in nuclear medicine, in heavy water for nuclear reactors, and in fusion reactions. So...

      Myth: Unstable isotopes are useless.
      Myth Busted!

      Past element 83, there are no stable isotopes. There's a pretty good chart showing the stable and unstable isotopes here [europhysicsnews.com]. There's also an interactive one, color-coded for lifetimes, here [kaeri.re.kr]. The half-life of these elements decreases from millenia to microseconds. However...

      It's been known for decades that certain numbers of protons are "magic" in that they "pack together" in a very stable manner. Same thing with neutrons. As we approach the next "magic" numbers, the half-lives of the elements should start going back up. And they do.

      In this latest experiment, the particular isotope of element 113 *may* have lasted for as long as 1.2 seconds. That's a long time for such a heavy element. Elements under 113 last for much less time, so that shows that we may be reaching the region of stability.

      The region of stability is apparently close by, and *stable* superheavy elements will assuredly have useful properties.

      And that's why nuclear chemists continue to search for heavier and heavier artificial elements. Because one day one of them will last for more than a few seconds. And then one day, one of them will last forever. Instant revolution in materials science.

      Myth: There's no point searching for superheavy elements.
      Myth Busted!

      Everyone seems surprised that nuclei are not always spheres. Lopsidedness is common in nuclei. O-16, for example, has a complete set of filled proton and neutron shells (making it the nuclear equivalent of a noble gas like the helium nucleus). If you add another neutron to make O-17, the neutron fills the first available orbital (an s-orbital) in the next, empty shell. This means it will tend to zig zag back and forth in a little straight line through the center of the nucleus. Since the other particles are always attracted to it and moving toward wherever it is, the rest of the nucleus gets distended from a round sphere and stretched in the direction of the neutron's motion. O-18 is even more football-shaped because there are two neutrons in that s-orbital now. Of course, in the case of s-orbitals there is little angular momentum to use as a reference, so the axis is indeterminate and it doesn't make any sense to say the football is "pointing" in any given direction.
      But many nuclei are distended by orbitals with definite angular momentum, and many are distended into shapes that are not footballs. Disks are common. The nuclei of heavy elements like uranium are shaped like light bulbs, with a definite axis. The "bulge" in the bulb sloshes back and forth along the main axis, onto each side of the center of mass.

    Rather than being round, nuclei in that region and beyond could contain bubbles and have strange doughnut-like shapes, Dr. Nazarewicz said.
    One of the theories is that our universe is shaped like a doughnut. Universe as Doughnut: New Data, New Debate [utexas.edu] So, the highest and the deepest reaches are similar in our conception.
    The discoveries fill a gap at the furthest edge of the periodic table and hint strongly at a weird landscape of undiscovered elements beyond.
    I recollect that Star trek [xs4all.nl] starts off with "Space, the final frontier. These are the voyages of the starship Enterprise. It's continuing mission: to explore strange new worlds, to seek out new life and civilizations, to boldly go where no one has gone before."
    Those numbers should help map out what Dr. Nazarewicz prefers to call generically a "region of stability" among the superheavies. (Because, he says, it could resemble a peninsula more than an island.) Various theories have suggested that the next magic proton number is 114, 120 or 126, he said. There is general agreement that the next magic neutron number is 184, he said.
    According to Douglas Adam, the answer is 42. [ans42.com] I would say the other possible answers are 84, 126, 168, & 210. So, the correct answer is 126.

      Heavy elements provide additional data points that let us test our understanding of nuclear structure and the interactions that hold the protons and neutrons together. The universe is basically powered by nuclear processes, so what we learn about nuclear structure is then related to astrophysics and cosmology.

      Take the case of a neutron star--it's made of extremely dense nuclear matter. As elements get heavier and heavier, they become better approximations of the environment of a neutron star.

    Assuming it was found, is that based on our understanding of the Periodic Table of Elements, those elements in the same Group or column have similar properties.

    So, based on that knowledge we can say that Element 115 should be very much like Element 83 (Bismuth), which is the most diamagnetic metal, giving it some very interesting properties.

    Also, it should be noted that Element 115 should it possess diamagnetism, and all indications are that it should, it will be a much better diamagnetic material than Bismuth.

We just need to get the quarks and the gluons into separate bottles, then just weigh the ingredients and get out the Magimix. All this colliding heavy nuclei at high speed may look good and make for big budgets, but all real progress is made with test tubes and Bunsen burners.
