Ytterbium has a special place in my heart - I did a report on it in high school (20+ years ago), because it was the 'most random' element I could think of. I had no idea it could be so lively!

[@STEVE_C_1369]

Whats great about ytterbium is its gaining use in semiconductor arena. Its also being used to replace other,very toxic substances,while its self,is very low in toxicity.

Neil sniffing the ammonium hydroxide to check if it’s still alright to use is the most Neil thing to do 🤣🤣🤣

[@MicraHakkinen]

That's how a coworker landed himself in the hospital. We were clearing out some old bottles from a seldomky used workshop and came across a large brown glass bottle. Instead of carefully smelling the cap, he proceeded to forcefully inhale with his nose right up to the bottle: it contained ammonia.

[@Kycilak]

@@MicraHakkinen My colleague once wanted to flush ammonia solution from a burette after a titration with is breath. Well... One has to breath in before one can breath out and he inhaled with the burette already at his lips. Thankfully it had no effect on his health. Don't blow into burettes, wait just a little for the reagent to trickle out itself.

[@kenmohler4081]

@@Kycilak This only slightly related, but you made me remember an event from my long past. I was a little kid getting his tonsils out and they were using ether as the anesthetic. I told you it was a long time ago. I was struggling with the mask so the anesthesiologist said, “Don’t you like that smell? Just blow it away as hard as you can.” I did. What is the next thing you do after you have blown all the air out of your lungs? Right.

As a fellow Neil, I can confirm I would do the same.

[@xl000]

he is just 75 years old. That's not close to end of life in the UK. It's 80 years for men, 84 for women, but it's an average. Ther is a death peak however at age 87.

[@xifel72]

Ytterby can be translated to Outer Village. "Ytter" = Outer. "By" = Village

[@Olhado256]

So the element is really Outervillageium!

[@alexpotts6520]

It's interesting, the "-by" suffix seems to have crossed the North Sea (possibly with the Vikings?) and appears in the names of British places too: Derby, Grimsby, Whitby, Rugby etc. In fact two of those four are towns on the east coast of Britain, which makes the Viking theory even more plausible.

[@beeble2003]

@@alexpotts6520 I'm not sure why you describe it as a theory -- it's a well-established fact.

[@pattheplanter]

There is an Utterby in Lincolnshire, though the Oxford Dictionary of Place-names explains it as "Utterby Lincs. Uthterby 1150-60. Probably ‘farmstead or village of a man called Ūhtrēd or Ūhthere’." They do have: Idrigill Highland. (Skye). ‘Outer gully’. OScand. ytri + gil. But they think the ytri in Itteringham Norfolk was a person. Utrincham 1086 (db). Probably ‘homestead of the family or followers of a man called *Ytra or *Ytri’. OE pers. name + -inga- + hām.

[@gwen6622]

outervillagium, and the other elements outrium, villagium, and lagium (which is basically how ytterbium, yttrium, terbium, and erbium are named lol)

[@PeteSmithPhD]

Ytterbium has a quasi-stable +2 oxidation state that can persist in water in the presence of a strong reducing agent like ytterbium metal. The Yb(II) ion is light green in aqueous solution. I think that is why the solution was light green when you were showing the metal dissolving in hydrochloric acid. The Yb(III) was being reduced by the Yb(s) to form Yb(II).

[@brainandforce]

With the right acid, you can make it persist for longer (I've found sulfamic acid does a decent job at stabilizing Yb(II) ions for long periods of time)

[@connieembury1]

What a delightful surprise! First thing this morning a new Periodic video! I've been binge watching the periodic videos and just passed Ytterbium the day before. Thank you Professor, Neil and Brady for a lovely start to the day.

[@plextoob]

In my experience with colour from combustion, heat can destroy the ions needed to get strong colour. We'd often mix in a buffer to try and reduce the reaction temp to extract more colour. Perhaps the PTFE does the same - the PTFE burns first in the flame and provides a cooling effect to preserve the ions responsible for the colour?

[@That_Chemist]

[@davidgillies620]

I don't know if PTFE is used in fireworks but I do know it is used in certain types of anti-missile decoy flares for military aircraft, as when combined with a metal powder such as magnesium it generates a lot of infrared.

[@stefanhurtig7956]

Many metals need a halogen donor to really bring out the flame color; in pyrotechnics, chlorine is usually used, though fluorine can also be found in some compositions. The exact compounds that form or the mechanism by which they enhance the color is to my knowledge little understood. It may be due to "forbidden" molecules that can only exist temporarily within the extreme conditions of the flame due to excitation or ionization. Maybe you guys could make a video about it.

[@pattheplanter]

I assumed the halogens just made the element more volatile by forming halides, so more entered the flame to get excited. The lumps of metal mostly combust with such a bright spark that they drown out the colour of the few ions that escape into the flame. Flame tests usually use ionic compounds of the metals rather than the elemental metals.

[@mrbullseye]

Erbium, Terbium, Yttrium, Ytterbium and if I'm not mistaken, Scandium (?), maybe also Holmium (even bigger ?), were all found in this mine. Quite cool but of course the isolation of them and their discoveries go out to the amazing chemists from all over the world who put in the hours.

[@turpialito]

One of the best professors I know of! I would like to study chemistry in Nottingham under his supervision.

[@bedlaskybedla6361]

Very nice experiments! I especially like Yb+PTFE green sparks, ytterbium chromate and unstable yellow Yb2+, which is formed during dissolving ytterbium in HCl (but it is quickly oxidized by oxygen and water to colourless Yb3+).

[@Bloated_Tony_Danza]

I once rolled ytterbium into foil, and once alloyed ytterbium with bismuth. It's a very easy metal to shape and form, doesn't corrode as fast as other lanthanides too. I like ytterbium

From flambéing pancakes with powdered sugar, in my experience it's most spectacular if you use fine powder and a tea sieve above the flame to prevent lumping. I thing instead of a file, a whetstone would yield finer filings. Or should we call these filings "stonings"? 🤔

[@Trav3l3r69.]

I recently did a school project where I studied the elements that were discovered in Ytterby, or at least could trace their discovery back to the mine there and this was one of the elements I did.

[@vinkuu]

Neil seems to be a super villain level authority on what to do and not do in the lab. I like him. Maybe tell us more about his background?

[@amundbjerve]

I studied Ytterbium (among other elements/isotopes) during my master's degree (a degree called Cand. Scient. in Norway at the time). Not as a chemist, but as a nuclear physicist. (I have no knowledge about the chemical properties of this element). The nuclei of these rare earth elements have fairly evenly spaced energy levels. This means that the energy shells are not very pronounced, and by targeting the nuclei with light isotopes like 3He and 4He nuclei, one can excite the Yb nuclei and "heat" them up. It turns out that you get some sort of phase transitions in the nuclei. Since there are only 170-something particles in Yb, talking about temperatures may not be entirely correct (strictly speaking, you need infinitely many particles to have a temperature, but any macroscopic object will suffice). Apart from that, the temperatures (or "temperature-like" parameter if you like) in question are several billion degrees (if my memory is correct; this was back in the late 90s).

Working with Yb as a physicist my own, the green looked similar, but not the same, as the wavelength of 556 nm, corresponding to the 1S0 -> 3P1 transition. TBH, I would have guessed to see a blueish/uv tint at 399 nm coming from the 1S0 -> 1P1 transition (the strongest one on the groundstate).

The green transition is right at the sweet spot for your eyes' photoreceptors...the near UV transition, not so much.

Are there any recent toxicology studies in humans for Ytterbium? I gave up looking 20 years ago. I don't know how it is in other countries but the internet in the U.S. acts like it's been lobotomized. My focus is on the triflouride in dentistry used for a radio-opaquing agent. Thanks.

[@Muonium1]

Ytterbium is quickly supplanting neodymium as a high power laser material, particularly in kilowatt scale fiber lasers where the pump efficiency is significantly higher. It has the very weird property in some of its compounds, along with some erbium doped compounds, of being an "upconversion phosphor". It can convert infrared light into visible light, seemingly violating conservation of energy to the mechanism-naive observer. I'm shocked to learn the base metal wasn't isolated until the '50s.

[@derderrr7220]

i'm curious as to how such things would react in pitch the luminescence of crystaline interaction at specific energy levels i'm curious as to if this element has a pressure reaction say if you hit a small bit with a hammer if it would or a large bit with a punch tool in combo with a hammer blow if it has discernible triboluminescence that is detectable without much hastle. great video!
