I actually just got done working with hydrogen telluride and tellurols last week, as well as telluroacetone. Loved your video Felix, as always! Only wish I had tried burning what I made, that blue flame is magical!
@@herrhaber9076 yeah, they decompose pretty quickly in air (the glassware at one point became coated in a tellurium mirror as the compounds decomposed), so smelling them was a bit challenging, but in the end I did get a few whiffs. Overall, they maintained the typical "leek-like" natural gas smell, but with a unique bleachy or metallic tint. Allyl tellurol was more garlicky, probably because the similar allyl mercaptan and allyl sulfides are actually found in garlic, but again, it had this organic bleach-like smell that was very weird.
Hydrogen telluride is thought to be the reason the Earth is depleted in tellurium compared to its abundance in carbonaceous chondrites. The gas escaped as the Earth formed. CdTe is the second most commonly used semiconductor for PV cells (after silicon), so if we had more tellurium we could make more of these. They are more tolerant of high temperature than silicon PV cells, so they have advantages in hot desert regions.
Finally, for years I have always wanted to see the properties of the heavier hydrogen chalcogenides especially hydrogen telluride on video, thanks for this awesome video! I see hydrogen chalcogenides get more unstable as we move down from water to hydrogen telluride.
Wow I just got done watching Poor Man’s Chemist’s video on testing his copper telluride right before this. This is impressive tellurium chemistry I love these demonstrations you do with exotic elements and compounds!
Did some of my own digging and posting again for safety; seems like there's a healthy bit of UVC in tellurium's emission spectrum, so probably not the best pretty light to stare at. Really sucks to have UV as my favorite color. (That "high energy" blue-gray of an overcast day has always been magical to me)
Really cool to see someone demonstrating this on TH-cam! I recently had to make hydrogen selenide through a similar process, and I thought that was nerve-wracking. One issue is that buying Al2Se3 or Al2Te3 is quite expensive, as you mentioned. However, it can be synthesized from the elements, but it requires a very high temperature. One must ignite magnesium in a crucible a few times to melt the elements together. And if it's done in an oxygenated environment, apparently it evolves a lot of chalcogen oxide fumes. I would be really curious to see how this goes. If you synthesize some aluminum telluride, I will at least try synthesizing aluminum selenide!
IIRC you can make tellurides, stannides, and bismuthides with other metallic elements as the cation! That might be a fun thing to try sometime, even if the chemistry isn't the most visually impressive. An ionic (or at least partially so) compound between two metallic elements is a really fascinating phenomenon and I doubt there's much out there about these compounds. A few even occur naturally so it shouldn't be too too hard to pull off.
Thank you so much for all of your hard work on this video. It was excellent. Tellerium has a beautiful flame. I never would have seen it if not for you. You're the best, Felicks!
Respect to you Sir, you're a brave man to risk your future social life by working with tellurium like this. Your fume hood vent must smell amazing. You didn't happen to be doing this in Bridgwater, Somerset a few decades ago by any chance?! Here were we blaming British Cellophane...
For those who don't know, this compound is the reason why Tellurium is very rare on Earth, because during it's early formation, tellurium reacted with residual hydrogen in its atmosphere to form this volatile compound that evaporated quickly.
Hey great video on substance so hard to work with. I hope your body odour remained normal after producing this video. Even very minor amounts of Te absorbed by your body can have quite the effect...
Wow! That manganese heptoxide reaction was absolutely beautiful. I appreciate that it must take a ton of skill to get such beautiful footage with such a violent reaction!
I had to be sure that the reaction would happen. I didn't have more hydrogen telluride for trial experiments to choose the best one for the video as I usually do 😏
Wow! This experiment looks like an insane mess in laboratory after it. But may be all of your shootings are like that. )) And as always our great appreciation for your work. It is the thing that we need to put our learning and teaching to the next level.
Your videos are always spectacular ! I do not want to be the guy who clean up all those glassware though. I would have checked if ZnTe was phosphorescent as ZnS is.
You should do some unusual metallic compounds that involved tellurium I was doing some mineral hunting and did some panning from a stream and came up with this unusual silvery mineral. I'd exhausted my guess is as to what it was and somebody online suggested I put it in sulfuric acid and see if it changes color or emits a smell and it did both. Gold telluride.
Try to mix ammonium nitrate and sodium benzoate, and then slowly heat it. It starts to smoke with thick white smoke as it slowly cools down, it looks like snow is falling.
He already did one heating higher fluorides of Manganese and Cobalt. I truly believe that Chlorine Trifluoride is beyond even his skills to handle (this is NOT a challenge).
8:40 this reaction reminded me of the Pillars of Creation - is a photograph taken by the Hubble Space Telescope. Did you really spend $1000 on zinc telluride? This is an incredible performance, simply exotic!
2:50 on Valentine’s Day 2005 I saw something flying through space that made this color. I could never explain it but I’ll never forget. p.s: I’m sure it wasn’t aliens
Hello sir I have question please. What's the best material to use as binder for cars breaks pads .remember it has to take very high friction heat and be soft in breaks rotors and of course no noise thanks 👍
it was almost what I expected! but you can store in vials and make an interesting lab tour with what you have done :)) (ladies and gentlemen welcome to chemical force collection :)) )@@ChemicalForce
Woh... once its cooled to liquid form it goes bat shit crazy, wtf is it crashing out and re-dissolving continuously? Just tipping it out looked amazing.
I recently finished writing a shooting plan for uranyl nitrate, now I need to see what I wrote works, choose the best reactions and shoot a video. I think I’ll do it by the end of the year! 😁
In all seriousness I would love to see more of the p-block hydrides such as arsine, stibine, stannane, plumbane, and alane (and bismuthine, gallane, indigane, and thallane but those are supposed to be extremely difficult to make)
Why would Tellurium and aluminum burn like that? 2 metals with no oxidizer… It looked like flash powder almost. I wonder how that would burn with a chlorate mixed in? Or would that be bad to do? I’m not a chemist… Just a firework enthusiast haha
I mixed powdered aluminum with small pieces of tellurium in a test tube and it didn't explode. In this case all you need to get hydrogen telluride is water, not acid. Woof, vile odor. Possibly the most dangerous substance I ever made. I didn't know about the photo decomposition. Interesting.
Tellurium is not a metal but a metaloid. It stands in the 6th main group and is kinda similar to the other elements in that group (Oxygen, sulfur and selenium). In the reaction with zinc or aluminium it acts as the oxidizer just as sulfur for an example would.
I actually just got done working with hydrogen telluride and tellurols last week, as well as telluroacetone. Loved your video Felix, as always! Only wish I had tried burning what I made, that blue flame is magical!
Oh my god, he's finally done it
May I ask you to tell us about telluroacetone by details?
tellurols ? That's something I'd like to see. From a very very long distance :)
Joke apart, I imagine they decompose quite readily ?
@@herrhaber9076 yeah, they decompose pretty quickly in air (the glassware at one point became coated in a tellurium mirror as the compounds decomposed), so smelling them was a bit challenging, but in the end I did get a few whiffs.

@@LabCoatz_Science Oh I never imagined they would decompose so fast that smelling them could be challenging.
Maybe it is for the best :)
Now do bismuthane.
that would be exciting to see preparation and reactions of BiH3, accordingly to the literature it is not so easy to make and very unstable.
probably would be more interesting to make Stannane, which would be easier to handle than Bismuthane.@@heorhiypavlovych9779
Yes!
Now that's an exotic reagant lol. But if there's anyone on TH-cam who could pull it off, it's ChemForce!
Followed by coordination compounds with BiH3 as the ligand
insane the amount of work you put in. great job
That must have smelled AMAZING to clean up XD
That was so cool! Thank you for taking the time and effort to show us these cool reactions.

Do they work at night and on cloudy days?
@@jc5445 im not sure you understand how solar panels work, how the fuck would it generate power at night?
@@jc5445 Do you work at night or on cloudy days?
@@jc5445 That's why there would be storage (of various complementary kinds, not just batteries for diurnal storage).

You are doing amazing stuff they probably would've done in the 40s if not for the war.
most unique and novel yet underrated chemistry TH-camr.
Such an underutilized and underappreciated element.
And now I will be actively looking into getting a tellurium vapor lamp; that emission spectrum is GORGEOUS!

Thank you! Excellent chemistry, perfect demonstration.
The cool cyan flame when burning it is amazing but that manganese heptoxide reaction really made the video! Looking forward to your next one, cheers!
Psst, inside information 🤐 the next video will be about WF6 chemistry.
Very impressive. Thanks for opportunity to saw this rare chemical reaction - this is not a typical 'let try to mix it with KMnO4' substance.

You sir have a multimillion dollar TH-cam channel. How does it feel to be the best channel on here? ❤
Cool video. I am too scared to work with H2Te. Hydrogen telluride.
Now i want to see the same thing done with H2Se.
(I know he already made hydrogen selenide in a previous video, but on small scale)
Long time fan. Thank you for your work.
That discharge tube is the definition of "ooh pretty colours."
My favourite TH-cam scientist!
thanks for showing me more substances id never like to meet in person xD much love
That oxy-hydrogen telluride flame was really beautiful, looked like some sort of futuristic space torch to (hot) weld in space lol
Laughing at: "reacts with manganese heptoxide" -- i think the list of things that don't react with it is quite a lot shorter!
I had to be sure that the reaction would happen. I didn't have more hydrogen telluride for trial experiments to choose the best one for the video as I usually do 😏

I’d love to see you test organic perchlorates one day, particularly ethyl perchlorate.
Amazing chemistry and filming 🎇😊
I think the hydrogen compounds like: Bismutan, Stiban, Stannan and so on are very interesting. would love some more videos about them
Monumental!
I think it would be awesome to have you and NileRed make a colab
Casually showing the plasma excitation, loved that!

"Hello, Derek Lowe? Got a new one for ye-"
The tellurium sample tube may have a buffer gas like argon. Did you try heating it to increase tellurium vapor pressure?
Finally, tellurowater.
Ahhhh telluride decomposes in the light, no wonder kia named a car after it. Makes sense now.
Okay. Cheers!
Damn, you really put a lot of effort in this video, cleanup must've sucked. Anyways, can you make a lab tour video next?
Thank bro😊
Awesome 💪💪💯

Woh... once its cooled to liquid form it goes bat shit crazy, wtf is it crashing out and re-dissolving continuously? Just tipping it out looked amazing.
4:59 That stoichiometry is off.
It should be 2 H2S + 2 HNO3 --> 2 S + 2 NO2 + 2 H2O
Metatelluric acid? I would love to see the tellurium analog of H2SeO4
organotelluric compounds,
Potassium ferrate, potassium tetraperoxochromate(V) please
Please HCN next. There is no good video showing liquid and gaseous HCN and it’s interaction with other chemicals
Great now do a Vid about Thallium hydride xD
I love how telluride sound like some elfish race in Elder Scrolls (or its just that I woke up and everything sound elfish....) :D

Can you do a video, about ceasiun hydroxide or pottasium ferrate 🤔
Is it a specific frequency or any light portion?
Can you try
Uranyl zinc acetate?
Production of pure calcium oxalate?

Will ignite pretty much 99.999% of any other chemical compounds
Maybe you yourself dont smell it, but how do other people react to you now? Have you tried taking public transport?
How bad did this smell?
H2Te smells like a freshly burnt match head (at least in low concentrations)
