Day 104 – RUTHERFORDIUM.

OK – we’re GOING BIG LEAGUE…..

  1. When I was in elementary through high school, the table ended at lawrencium, which was kind of tidy. The actinides were full, and that seemed like a good stopping point.

    However, if you poked around in places like the CRC Handbook and even the Guiness Book of World Records, you could see where Communist Russia had claimed to have created element 104, and so had an American team. They argued for so long over the right to name it (the Russians liked the name “kurchatovium” after one of their atomic bomb team), that eventually the International Union of Pure and Applied Chemistry, which is ultimately responsible for deciding the official names of chemicals (including elements), threw up their hands and came up with temporary names based on the element numbers. 104 became Unnilquadium, from un=1, nil=0 quad=4 plus the -ium suffix. This system is still used today for elements that have not yet been verified and named (there are none like that at present).

    Eventually, in the 1990s (decades later!) all of the controversy for elements numbered over a hundred was settled and we now know 104 as Rutherfordium, after Ernest Rutherford, who discovered the half life, the element radon, the nucleus, distinguished between alpha and beta radiation, and helped show that alpha radiation is helium nuclei.

    He certainly deserves to have an element named after him.

      1. There was a company back then (maybe they’re still in business) that would make T-shirts for geeks, such as “And god said and there was light” and one with the periodic table. It showed Ku in block 104, and I remember remarking “looks like the Russians won that one.”

  2. The most stable isotope of Rf has a half-life of about 1.3 hours. It is named after the “New Zealand scientist”, Ernest Rutherford — raise your hand if you knew he was born in New Zealand…..yeah, me neither. He did early work in Canada that distinguished between (and named) alpha and beta radiation, for which he won a Chemistry Nobel in 1908. Meanwhile, in 1907 he had moved to Manchester. He later moved to Cambridge in 1919 where he named the proton, and is buried in Westminster Abbey. To complete the circle, his parents had moved to New Zealand from Perth, Scotland “to raise a little flax and a lot of children”.

    To have the Wikipedians go on about him like he was half Maori by way of pixiedust is just embarrassing. Rutherford is, and was, a Brit.

  3. Rf-267 is the most stable nucleus, with a half life of 1.3 hours. A very little amount of chemistry has been done, and it seems to fit reasonably well with zirconium and hafnium, its upstairs “neighbors” in the periodic table.

    It appears that the first reaction to produce rutherfordium was Pu-242 (94 protons) + Ne-22 (10 protons) –> Rf-264, which they immediately reacted with chlorine to form rutherfordium tetrachloride.

    is a chart of nuclides. As you go up, you’re adding neutrons, as you go right you’re adding protons. Hydrogen is at the lower left. The stable nuclides are in black, the ones nearly stable are in red. Basically the bluer, the more unstable.

    You can follow a line straight along the black squares, then when they run out, you can follow the red, orange and yellow squares. And you can see that that line starts to run into the top/left edge of the colored part of the diagram. That’s a graphic representation of what I was trying to say yesterday; we can’t pile enough neutrons on to these super-heavy elements to figure out what their most stable isotope actually is.

    1. If we assume that Lazar’s briefings were only part bullshit, and the “passed snippets” from other researchers less so, then there are certain contradictions which I’ve pretty well resolved to my satisfaction, thus having an idea what was disinformation and what was not. I’m going to save some of that for later discussion, but one of the points made RE the alleged Mc isotope was that it was stabilized by storing in a neutron flux. Again, don’t want to touch that specific case now. Would prefer to save for the specific case! But it provokes the question of whether we (humans) are missing some simple and “Oh, shit, I could have had a V-8” neutron generation technology that allows for more significant “piling up of the damn things” than what we have now. Not saying I have any good ideas ATM what that would be – it’s just a sudden thought that a cheap, easy, and high-flux neutron source out of left field would sure make exploration to the left of that “observed and stable” line, where the good stuff obviously lies, a LOT easier.

      1. exploration to the left of that “observed and stable” line, where the good stuff obviously lies, a LOT easier.

        The point I’m trying to make is that at those atomic numbers, we haven’t even got TO that line! When people first realized this they were hypothesizing potential half lives in the billions of years (stable enough for us to do something tangible with those elements without needing lots of shielding), now they’re much more conservative and are talking days or minutes.

        We don’t know, and ought to find out.

        1. Those results for 105 also pattern well for something up there. Those results came in during the ’70’s – totally fits with the Lazar story.

          Another interesting point is visible in the synthesis track record of 105:

          https://en.wikipedia.org/wiki/Isotopes_of_dubnium

          The whole neutron evaporation thing is just tempting – one can see the “cold fusion” strategy there – to try to land stuff on a kinetically stable shelf. This is where I think going “pseudo-thermodynamic” with a massive gentle neutron flux could push stuff back to 0n from low-n exits. And if that stuff – the original target – is a neutron suck, then AWAY YOU GO – you are ONSHORE – or at least on a sandbar.

          Bigger picture – pristine universe – no “proton-universe” assistance (COUGH) – pathway has to be there, IMO – maybe one needs to get some of this stuff in an “old-fashioned” way on some planet lacking primordial – THEN you get the moxie to find “primordial” out there somewhere. I just get the feeling that the “design” aspects of the table that stave off primitive self-destruction might not be so restrictive on the next island as to block it off completely from investigation in a system like ours. But I could stand to be corrected if these jokers with their bioweapons and clumsy “anti-life to save humanity” dupe attitudes don’t learn a lesson or two here. Then a strategy that depends on distances and random life near primordial makes sense to “moderate” things. But I keep coming back to seeing a universe that pushes life hard. I think uniqueness attitudes are pure terrarium disinfo. Time to look through the glass and blink at the keepers.

          Not sure the interesting times ever end! 😉

  5. Our good friends in Berkeley tried to synthesize Rf by smooshing Cf with carbon in 1969. The Dubna group was smooshing Pu with neon in 1964 to the same end. Once again, the official name went with the West’s version.

  6. So a man walks into a bar with a burlap sack. He pulls out a small piano, bench, and a tiny piano player, who begins to play songs on the miniature piano.

    The Bartender, intrigued, asks the man where he got it. The man proceeds to show the bartender an old genie bottle. Out pops an old, dusty genie. The man tells the bartender to make a wish.

    The Bartender wishes for 1 million bucks. All of a sudden, Ducks begin shooting out of the top of the bottle. Frustrated the bartender yells to the man “I wished for a million BUCKS not a Million DUCKS!”

    To this the man replied, “Yea, and i didn’t wish for a 12-inch Pianist Either.”

  7. Steve’s graphic really begs the question of what is going on with atomic weights between 125 and 135.

    Anyhoo — The Powers That Be have not announced any safety standards regarding personal exposure to Rf — so just grab an atom and sunbathe in its radiation.

    1. That’s a great question. I never thought of it that way. I always think of it the other way, as in “why is this long linear island GOOD, rather than – why is this region seemingly NOT GOOD.

        I consider this more of a benefit than a detriment to a midnight open thread. It ain’t like you’ll be hearing it on your local AOR radio station.

  8. Two elderly women were eating breakfast in a restaurant one morning.

    Ethel noticed something funny about Mabel’s ear and she said, “Mabel, did you know you’ve got a suppository in your left ear?”

    Mabel answered, “I have a suppository?” She pulled it out and stared at it.

    Then she said, “Ethel, I’m glad you saw this thing. Now I think I know where my hearing aid is.”

  9. This is an INCREDIBLY IMPORTANT and self-undressing first person propaganda (account) of Senator Chris Murphy’s trip last week to UKRAINE and the Munich Security Conference where he had a direct, one-on-one meeting with IRAN FOREIGN MINISTER ZARIF. Other than noting the ass-covering, I-didn’t-break-the-Logan-Act purpose, I would love to hear the collective thoughts on this as I see it as Murphy unwittingly telling us very much under the category “He Doth Protest Too Much”.

    1. I can’t let this go!!!! Says Chrissie:

      “I don’t know whether my visit with Zarif will make a difference. I’m not the President or the Secretary of State — I’m just a rank and file U.S. Senator. I cannot conduct diplomacy on behalf of the whole of the U.S. government, and I don’t pretend to be in a position to do so. But if Trump isn’t going to talk to Iran, then someone should. And Congress is a co-equal branch of government, responsible along with the Executive for setting foreign policy. A lack of dialogue leaves nations guessing about their enemy’s intentions, and guessing wrong can lead to catastrophic mistakes.”

      Since when did Congress ever, anyhow, anywhere acquire a joint responsibility for foreign policy – especially a Tuckfurd like the little mushroom from Connuticut???

      1. If SILENCE is our official message, Senator Chrissie is CONTRADICTING IT.

        Seriously – this is just COVER for DOUBLE-DEALING. He’s playing the “concern bot” while RELAYING MESSAGES to and from Kerry, Pelosi, Obama, Jarrett, Sherman and the rest of their gang.

          THE PRESIDENT: ……So we are negotiating with the Taliban. We’ve been negotiating with them for a while. We will see what happens. There’s a chance of making a deal. There’s a chance.

          I can’t believe — so quiet, all of a sudden.

          Q Senator Graham is traveling with —

          THE PRESIDENT: I saw that Senator Murphy met with the Iranians. Is that a fact? I just saw that on the way over. Is there anything that I should know? Because that sounds like, to me, a violation of the Logan Act.

          Q Can I ask about Venezuela, sir?

          THE PRESIDENT: Yeah, what happened with that? Did you read about Senator — or hear about Senator Murphy met with the Iranians?

          Q No. Tell us about it.

          THE PRESIDENT: Well, they ought to find out about it if it’s true. I don’t know. It just came out as I was leaving the car.

          Q Can I ask about Venezuela, sir? Do you think Guaidó is still the guy to get Maduro out of office?
