Controversy-Plagued Element 118, the Heaviest Atom Yet, Finally Discovered


Element 118 has been created in experiments conducted at the Flerov Laboratory of Nuclear Reactions in Dubna, Russia by a collaboration of researchers from Russia's Joint Institute for Nuclear Research and the Lawrence Livermore National Laboratory in California.

Element 118, the heaviest element yet found, was produced through collisions that fused together Californium and Calcium atoms. Although element 118 is too unstable to detect directly, the presence of daughter elements resulting from the decay of element 118 gave clues to its fleeting existence.

Researchers at the Lawrence Berkeley National Laboratory previously reported the synthesis of element 118 in 1999, and later retracted their results when subsequent experiments failed to confirm their discovery. It was alleged that researcher Victor Ninov fabricated the experimental data that indicated the formation of element 118 atoms.

The (re)discovery was reported in the American Physical Society journal Physical Review C on October 9, 2006.

  2. Congratulations. I wonder who this one will be named after... The last few were Roentgenium and Darmstadtium, so I wonder if this will be named after the place WHERE they discovered it or WHO discovered it...
    Or, if the IUPAC wants *direct* proof that it was synthesized. I guess we'll have to wait and see.

  10. Take the example of Sweden's lovely village of Ytterby, which inspired the names Terbium, Yttrium, Ytterbium, Erbium.

    Dubna doesn't give us much to work with - Dubnium, Ubnium, I guess.

    But Livermore: Livermorium, Vermorium, Liverium (Livorium), Morium, Livium, Ermorium, Iverium, Ivermorium, ....

    And that's not counting whatever names can be gleaned from the local wineries as well as the nicknames of obscure hardware, computer, and physics toys "out back in the shack i mean warehouse."

  16. I honestly don't understand the use of creating heavier elements. Each and every element that is heavier than the next is also more unstable the next. Hydrogen is then obviously the most stable.

    The reason is quite simple. As you pack on the protons and neutrons the nuclear forces begin to dwindle significantly. With elements such as 118, they last only a microsecond before gravity and the other forces tear the atom apart.

    If you're thinking we can make use of this with new steel components that will resist thousands and thousands of degrees of heat or something, it isn't going to happen :(. The most useful elements, and they still are, are well under atomic weights of 100.

  18. Actually, Hydrogen isn't the most stable. That honour belongs to iron (Fe-56).
    Elements on either side tend towards iron; thus we can obtain energy from Hydrogen fusion, or Uranium fission. However, the heavier (>118) elements may have "islands of stability", so some of them may be unexpectedly long-lived.

    ReplyDelete
  19. Actually, the real race is on to create element 114. There is a theory that it has a balance of protons and neutrons needed to be within an 'island of stability' that will allow the created element to exist for quite some time.

    As it turns out, the internal nuclear structure of an atom is an ordered collection of protons and neutrons, instead of a random jumble.

  22. "The reason is quite simple. As you pack on the protons and neutrons the nuclear forces begin to dwindle significantly. With elements such as 118, they last only a microsecond before gravity and the other forces tear the atom apart."

    Gravity hardly matters on that scale...the force that you're looking for is known as the 'coulombic force' (electromagnetic force). Also, forces don't 'dwindle' when more bodies are introduced...they tend to decrease with an increase in spacing between the bodies involved.

    More 'nucleons' or nuclear particles (protons and neutrons) means greater spacing between the outer ones which in turn means less nuclear binding force between those particles to counteract the coulombic force.

    Finally, your contention that things that exist ephemerally cannot possibly be of actual human use ignores key human technologies.

    Like candles.

    Thank goodness we haven't yet succumb to the wisdom that "photons only exist for a fraction of a second, so why make them?"

  25. Regarding element 114: Computations do suggest that 114 is a "magic" number of nuclear structure, and so elements with this number of protons should be more stable. The key word here is "more" - the half life will probably be much longer than nearby heavy elements, but still very short.

    You might be able to make an isotope of element-114 with a very long half life, perhaps even a stable isotope, if the number of neutrons is also a magic number, say 184. The problem is that it's very hard to make a nucleus with a neutron/proton ratio that high. For example, you'd have to collide Californium-255 with something like Sulfur-43, which doesn't exit.

    ReplyDelete
  26. Hardly any information on this. What is the estimated half life? What a lame "article." Need more information.

    Here is my article "ELEMENT 190 made today in my house."

  39. A wise man once said:
    "Element number 118 will bring great destruction to the Earth when it is discovered so do not eat it". He also said:
    "Name the element ExplodetheEarthium, or you will suffer the wise man's wrath".

    My favourite element is Titanium.

  44. Photons do not exist for a fraction of a second. They exist for an instant. A literal instant - they are created, travel, and are destroyed simutainously, with no time at all passing between.

    Hence the question used to annoy those who dont know the basics of relativity: How old is the light from a star x light years away?

  61. The higher the atomic number, the more electrons an atom has. The more electrons, the more shells. The more shells, the larger the atomic radius. The larger the atomic radius, the weaker the grip on the outer electrons.
    This means that the attraction between the protons in the nucleus and the electrons in the outer orbitals is too weak to keep the electrons in orbit.
