Day 89 – ACTINIUM.

  1. Aaah, we have actinium Qed up finally.

    Cthulhu had actually posted some actinium stuff on yesterday’s thread, so I joined in.

    Anyhow, here’s my post from 2600 hours yesterday, with one typo corrected.:

    It looks like cthulhu has taken actinium…er, action here.

    There’s little to say about it that doesn’t apply to the other “between bismuth and thorium” elements, other than that there is at least enough that people have laid eyes on it; apparently it’s so radioactive it glows with a bright light and that’s where the name comes from–from the Greek for beam or ray.

    I’ve seen the word “actinic” used to describe a painfully intense or bright light.

    Actinium is also the first of the actinides, the “big brother” of the lanthanides that were so tedious to go through, However, there is enough distinctiveness among the actinides (on account of features of their radioactivity) that it shouldn’t be as bad most of the way through the series–well, up through californium)

    And again we have the debate over whether lawrencium and actinium are the first transition metals (belonging rightfully under scandium and yttrium) or whether that should go to lutetium and lawrencium. I really don’t want to go into that a third time! (But if you haven’t seen it: https://utree.home.blog/2020/01/16/open-thread-20200116/#comment-4017) But if the people who think actinium should be the element to go under scandium and yttrium are correct, then, ironically, actinium is not an actinide, and lanthanum is not a lanthanide!

  2. Actinium is found in nature — about 0.2 milligrams per tonne in uranium and about 5 nanograms per tonne in thorium. So it’s actually cheaper and easier to make it out of radium than it is to separate it. Once you get the radium to “bloink” into actinium, it has a respectable half-life of 21.772 years.

  3. Musical interlude 1 —

    This is another Little Feat tune — though sung here by Linda Ronstadt. I understand that it’s not a Lowell George tune, but rather by his bandmate Paul Barrere — but George does vocals on the original album version and most live recordings.

  4. Supposedly, actinium is a silvery-white metal, but there is so much blue glow around it I have to wonder about the observation. It may be that someone went to the trouble of observing it in a vacuum, where it had no nearby atoms to excite into glowing.

  5. A plumber was called to a physician’s home to fix a leaking faucet that had been keeping the doctor awake late at night. After a two-minute job the plumber demanded $150.

    The surgeon exclaimed, ‘I don’t charge that much per minute, and I’m a surgeon.”

    The plumber replied, “I really feel for you. I couldn’t, either, when I was a surgeon. That’s why I switched to plumbing!”

  6. When your main source of an element is transmutation (from another rare element) in a nuclear reactor, you can just imagine how expensive actinium is. It should be no surprise that there has been little drive to involve it in industrial processes. As long as grants are out there, however, scientists will endeavor to produce research papers.

  7. A doctor had a backed-up toilet and knocked on his neighbor’s door in the middle of the night. The neighbor, a plumber, complained that he was sleeping and it’s his day off, but the doctor replied, “I’m a professional and I’m always on call!” The plumber wearily got dressed, went over to the doc’s toilet, lifted the lid, tossed in two aspirins and said, “If it’s still like this in the morning, make an appointment with my office.”

  8. OK, people – we are all scheduled out to the END of the current periodic table – OGANESSON.

    The question becomes, what do we do on MARCH 4, 2020? That is THE DAY AFTER OGANESSON.

    In particular, at that point in time, is there any possibility of U TREE DAILY THREAD AUTHORS?

    OR (and this may be what people like) just go with some easy daily thread like GEEK ITEM OF THE DAY? This would just be some random item from my memory – frequently just a CHEMICAL, that I would throw out for people to POUNCE ON.

    Let me know what you all think……

    1. Pick a random list — US states by entry date; books of the Bible; Nobel Prize winners in something useful (physics, chemistry, or medicine); tarot cards of the Major Arcana; popes with the same name as a Beatle (John or Paul; not George or Ringo)…..and, in the words of the Magic 8-ball, “Ask Again Later”.
