NPR Sunday Puzzle (Mar 24, 2024): Periodic Puzzle

NPR Sunday Puzzle (Mar 24, 2024): Periodic Puzzle
Q: Each chemical element can be represented by a one or two-letter symbol. Hydrogen is H, helium is He, and so on. There are two commonly known elements whose names each can be spelled using three other element symbols. Name either one.
Could they be Zirconium and Tungsten, but a small quantity?

Edit: Zirconium (40) and Tungsten (74) make 4074. Convert that to hexadecimal (FEA) and add a small quantity (gram = g) and you have Fe,Ag
A: Iron = Ir (Iridium) + O (Oxygen) + N (Nitrogen), Silver = Si (Silicon) + Lv (Livermorium) + Er (Erbium)

    1. Double-check the puzzle wording if you are finding others

      Delete
    2. There are many others if your "usage" includes anagramming.

  3. Got them both, but as a Chemical Engineer I had an advantage. The two elements are often paired.

  4. Rearrange the two elements, and get a third element and a landmark or, alternately, an animal.

    1. Hmmm... I don't get a third element, but I do get a town in South Africa or a geographic feature in France.

    2. I've been wrong before, but I double-checked. Blaine notwithstanding, alternate answers?

      Delete
    3. Dr. K, are you saying to rearrange the element names, or the letters of the symbols? I'm not getting a third element using the names.

      Delete
    4. JAWS, I just triple-checked. Rearrange the letters of both elements' names (I realize you need only one of the two to solve the NPR puzzle), and get two words for a third element and a landmark (or alternately for "landmark," an animal). I shouldn't say more.

    6. JAWS, et al., my hint above is based on an interpretaion of the word "spelled" in the puzzle's wording that does not lead to the intended answer. My apologies.

  6. About 260 correct entries last week.

  7. Got it. Like others, I feel this is not easy to clue.

    ReplyDelete
    Replies
    1. Take the atomic numbers of the two elements, and write them consecutively to create one number. Since this creates two different possible numbers, I predict that the number of correct guesses this week will be between those two numbers.

      Using Blaine's listed elements as an example, Zirconium is 40, and Tungsten is 74. If those were the two elements, the numbers would be 4074 and 7440.

      Delete
    2. With very little rearranging of the letters within the element names, I get a relative, something on my computer, and something that is picked.

      Delete
    3. Please disregard both of my comments above. Last night, after being out most of the day, I re-read the puzzle before typing up my submission, and I realized I had missed one important detail in the puzzle wording--that three elements needed to make up the name. The clues above both fail that criteria. It is interesting how many of the other clues seem to point back to one or both of these.

      I have since determined the correct elements. But, given my track record on this puzzle, I might not clue further.

      Delete
    4. I will say I'm taking the under. I think a lot of people are going to put in one of the submissions that is incorrect.

    4. Thanks, Blaine. I now have the intended second answer, too. My apologies, once again, to Blainevillage. I seem to be suffering from anagrammania. (And again, like last week, I seem to be unwittingly offering alternate puzzles.) In any case, as is, the puzzle should have been more precisely worded. As if my NCAA brackets weren't trouble enough...

    1. Sammy Hagar couldn't drive 55, and I couldn't see how silver could be an answer with "55" in the middle of it because I was unacquainted with Livermorium.
      I had already gotten Iridium-Oxygen-Nitrogen.
      I initially had hopes for TIN, but couldn't find an element symbolized by a lone "T", and the puzzle stipulates THREE component symbols.
      I also tried Xenon and rejected it on the basis of non-otherness. Same goes for Neon.

  33. I found two, although one of them uses the letters for its own symbol, and the puzzle says "using three other element symbols," so I'll stick to the one that doesn't do that. Also, I found one element that uses the element symbols for four other elements. Fun!

    1. It's clear they were having electrical power problems, which led to loss of control. On the live video feed of the Port of Baltimore", you can see the ship's lights go out at 1:24:32 EDT, back on at 1:25:31, off again at 1:26:37, and back on again at 1:27:10. At 1:26, the ship is seen turning to starboard, out of the main channel, and directly toward the southern main bridge pier, which it strikes at 1:28:43.

    2. Maryland Governor Wes Moore said that after a mayday call was made ahead of the collapse, workers stopped cars from continuing onto the bridge, a rapid response that he said had saved lives. On that video feed, the last vehicles are seen entering the bridge at 1:27:28, and exiting at 1:28:09, seconds before the collapse. (The stationary flashing lights of a few work vehicles are seen on the bridge right up through the collapse, so those workers were apparently not notified in time.)

  46. IRON composed of Iridium (Ir), Oxygen (O) and Nitrogen (N); SILVER composed of Silicon (Si), Livermorium (Lv), and Erbium (Er).

    "What a range of answers proposed this week! I like my two the best." pointed to both the Lone Ranger and Hi ho SILVER. Also, the number two medal in a race is generally SILVER.

    ReplyDelete
  47. Si (Silicon) + Lv (Livermorium) + Er (Erbium) = Silver
    Ir (Iridium) + O (Oxygen) + N (Nitrogen) = Iron

    Last Sunday I said, “Musical clue: C. Rossini.” Stick with me here. Rossini wrote the William Tell Overture, almost certainly his most famous work. The William Tell Overture was the theme song of The Lone Ranger TV series. The Lone Ranger’s horse was named Silver.

    I also said, “I got the other one, too. Television clue: 60s and 70s.” Ironside ran from 1967 to 1975.

    and

    SILVER (Ag) —> SILICON (SI) + LIVERMORIUM (LV) + ERBIUM (ER)

    Hint: “A puzzle like this may be pretty easy but, nevertheless, I find that it ages me.”
    —> hinting at two of the “Ages” of Man according to Hesiod and Ovid —> SILVER Age and IRON Age
    (I had considered wording it “I find that it can age a man,” but I thought that would be TMI.)

    Hint: “A certain nursery rhyme comes to mind.”
    —> “London Bridge Is Falling Down,” versions of which include references to SILVER and IRON

    An alternate answer, but one that involves rearrangement of letters:
    CARBON (C) —> CHROMIUM (CR) + BARIUM (BA) + NOBELIUM (NO)

    My hint for “carbon” and “iron” (which I initially thought were the puzzle’s answers): “Rearrange the two elements, and get a third element and a landmark or, alternately, an animal.”
    —> BORON + CAIRN (which is both a landmark of stones and a type of dog)

  51. IRoN, SiLvEr The metals anagram to Lions River, a small town in South Africa. In 1962 Nelson Mandela (who featured in a recent puzzle) was arrested a mile outside of town. This ultimately led to his Robben Island imprisonment. Today a monument marks the spot.

  57. I submitted silver, but copper is technically correct

    ReplyDelete
    Replies
    1. Excuse me, but how the hell is copper technically correct?
      That would be:
      copper —> Co + Pp + Er
      While Co is Cobalt and Er is Erbium, there IS NO element with the abbreviation Pp!

      Delete
    2. P is Phosphorus, and I don't think the wording of the puzzle prohibits using an element twice.
      I wish I had thought of that!

    3. Even then it would be expressed with 4 elements, not 3.

      Delete
    4. If an element may use FOUR element abbreviations is allowed, then:

      Carbon ----> Ca + Rb + O + N
      6 20 37 8 7

      Delete
    5. It only uses 3 element symbols; it just uses one of them twice.

      Delete
    6. No, Copper can be expressed with three elements: Cobalt, Phosphorus, and Erbium. If you were building the word using full blocks from the table, like the opening of Breaking Bad, then you would need four blocks. However, two of the blocks would be the same, so you would "use" only three elements.

      Delete
    7. Hmm... I may be changing my mind.
      The second P would obviously be "other" than Cu, but wouldn't it be "the same" as the first P?

  63. I eventually submitted IRON, one of the correct answers. At first, I had found Tin and Silicon, which can both be spelled using elements that are not themselves, but do not meet the requirement of using three of them. I missed that requirement while listening to the puzzle. Thinking I was done, I went about my day.

    I commented on SuperZee's clue about the two elements being paired together, that it was "clear to me," because silicon and tin are used together in making glass.

    Sunday evening, I went to enter my submission, and discovered the three element requirement. I quickly found iron and sent it in.

    I searched a little more, and found COPPER can be made, as noted above, using the symbols for Cobalt (Co), Phosphorus (P) [twice!], and Erbium (Er). Now I'm wondering if anyone will get credit for it. I think it is a valid answer, given the phrasing of the puzzle.

    I had also commented that I'm taking the under, because I think a lot of people will make a mistake similar to mine, or will submit Neon or Xenon, which use their own symbol.

    Finally, I didn't say anything because I was concerned it would be TMI, but there is no way to spell "ium" with the symbols on the table, so most of the elements were not in contention in the first place.

  64. CA+RB+O+N works. (Using 4 symbols by definition includes using 3. The word "using" does not mean using only.)

  66. My circuitous clue: Kelly 11
    Kelly Slater is an American professional surfer, best known for being crowned World Surf League champion a record 11 times. He is a “surfer man”, and Avengers Annual #11 comic is a matchup of the characters “Silver” Surfer and “Iron” Man.

    Regarding alternate answers, if "using" other symbols extends to anagramming them, then other common elements are possible answers, including boron (from Br, O, and No), carbon (from Ca, Rb, and No), cesium (from Cm, Eu, and Si), copper (from Ce, Po, and Pr), and radon (Ar, Nd, O).

    If you consider the four elements of classical cosmology, you can form "water" from "W" (tungsten), "At" (astatine), and "Er" (erbium).

  69. This week's challenge: In honor of women's history month, all our challenge contributors in March have been women. To close out the month, I have this related challenge.

    The English language developed in a patriarchal society, so many words in our language were traditionally assumed to be male, and turned into female versions by adding a prefix or suffix. Waiter and waitress, comedian and comedienne — those are just two examples of the many stereotypically "male" words that become new "female words" by adding a suffix.

    There is a common English word that works the opposite way. What is the common English word that is generally used to refer exclusively to women, but which becomes male when a two-letter suffix is added?

    1. IRON was pretty accessible. If both answers had been required, I think the number would have been significantly lower. I don't think Greg's examples this week are very good, though, as neither one really follows the rules. PRINCE and PRINCESS and HEIR and HEIRESS would have been better.

For NPR puzzle posts, don't post the answer or any hints that could lead to the answer before the deadline (usually Thursday at 3pm ET). If you know the answer, submit it to NPR, but don't give it away here.

You may provide indirect hints to the answer to show you know it, but make sure they don't assist with solving. You can openly discuss your hints and the answer after the deadline. Thank you.
