Do not repeat the experiments shown in this video!
Today I am going to talk about such a rare-earth metal as lutetium. Lutetium is the last element in the lanthanide series of rare-earth metals we have become quite familiar with, and that is why it has some unique properties. The elements belonging to this series are arranged in a specific order, in accordance with which, the atomic radius of elements decreases from left to right. Lutetium has got the smallest atomic radius which is why it’s got the highest density, hardness and melting point among all the lanthanides. This property is called lanthanide contraction because of the increase in the number of f orbitals from left to right. Anyway let’s not talk about the boring stuff anymore and let us take a look at the metallic lutetium, which when pure, looks exactly like other lanthanides such as erbium or terbium. By the way this element was discovered by three different scientists from different countries but this element was named by a French chemist. As was customary back then, he named it after his home city - Paris. He named it after its Latin name which is Lutetia. Chemical properties of lutetium are very similar to those of other lanthanide metals, that is why it is very hard to separate it from ytterbium. That is the very reason why its market price is so high roughly 10 dollars for 1 gram, which makes it just 4 times less expensive gold. It’s okay if you don’t know chemical properties of rare-earth metals because they are all very similar with the only exception of europium. Lutetium dissolves well in acids forming chloride of this metal. In contrast to other coloured lanthanide compounds, lutetium compounds are colourless that is why this metal was discovered only in 1907. Actually you might be surprised to learn that lutetium can be ground against a grinding wheel and it can form bright sparkles from bits of this metal, which burn up beautifully forming lutetium chloride. Speaking of this metal’s applications, pure lutetium is added to chromium alloys to increase their density. Lutetium is also added to alloys of iron and aluminium to produce strong magnets used in aerospace engineering. Lutetium oxide has a relatively narrow range of applications in nuclear technology, in particular it is used as an activation detector. Lutetium oxyorthosilicate is great for making detectors especially if its crystals contain cerium which triggers activation. Such crystals are usually used in positron emission tomography. Numerous clusters of such crystals are used. Such crystals start emitting faint light when irradiated with gamma rays, which are formed as a result of annihilation of electrons and positrons inside the patient’s body upon the decay of some isotopes, for instance such as fluorine-18. Faint flashes of light are boosted by the detectors, thus creating 3D images of the patient’s body which can show any irregularities such as cancerous tumors, etc. In nature lutetium consists of 2 isotopes. The first one is a stable isotope lutetium 175, which makes up 97,41% and the other isotope is a radioactive lutetium 176 with an enormously long half-life of 38 billion years, it makes up 2,6% accordingly. It is noteworthy that when a precise dosimeter with an open cap is put next to bits of lutetium, radiation increases by 4 times, which is quite unusual. That happens because pure lutetium extracted from naturally occurring minerals contains radioactive isotopes. There is no need to worry, however, the same thing is the case with many metals. For instance fertilizers containing potassium chloride emit radiation as well, because naturally occurring potassium contains an isotope potassium-40, but such a radiation dose doesn’t exceed safe exposure limits unless you live in a fertilizer store facility. However, there are artificially created isotopes too. One of them is lutetium 177.

I love this channel, been subscribed for 2 years now and it never gets old, great video, see ya in the next one.
One of my favorite channels by far! Thanks for the awesome info. Helped make this day a little better.
I love your videos, I've learn a lot about chemistry with them. Thanks and continue that way!
Thanks again for the great upload!
These videos are so good! I've been binge watching for 3 days now.
Unless u live in a fertilizer store facility 😂😂
Chronic exposure to large amounts of low hazard materials can still be very significant and lead to major health problems many years after exposure started.
he means the "balls" ???
I love watching this channel as it covers chemistry and applications you would never know about unless you worked in the field of rough chemistry ⚛️ thank you 🙏🏻
One fun fact about Lu scintillation crystals. They have a little bit of natuaral radioactivity that allows the measurement unit to have its own calibration source. 🤓
Well done mate, these vidoes are fascinating and nearly always hit just the right level !!
Great video, I love your films! Greetings from Poland :)
As always,Love your videos! Your cat is awesome!
It's the boring stuff that we learn in schools, friend. Thanks to you, I'm able to cultivate an actual interest in chemistry. Thank you for creating such great content.
Hi great to be here we live nearest the Mountain Pass Rare Earth REE mines. That is Americas REE mine producer. They only claim to mine 4 rare earths and Lutetium is not one of them currently. We are so proud to actually be able to learn here through these videos and extended research following these videos.Thank you for the share Lance & Patrick.
Yes your videos are very educational thank you keep up the good work🤓
I am learning a lot of facts about elements from this channel. Thanks
I don't find these videos boring please continue to explain 😃👍
Another excellent video.
TY for the video again!!!
Love your videos, and your cat! :3
A big big big fan of your channel
You make interesting experiments and topics but only late at night id be able to watch. So I watch this before sleeping. And it's on auto play till i fall asleep. Its ur voice . Makes.me.happy and let.me.drifts . Sorry off topic.
@Thoisoi2 - Chemical Experiments! I was surprised you haven't made a video on Nickel?! Or maybe I just couldn't find it. I was working on alkaline electrolysis with Platinum anode and it was developing a translucent blown-red layer on it, and so it searched for "Pt Thoisoi2" and there it was - "Platinum will oxidize in alkaline conditions..." was thinking about using a nickel anode, couldn't find your video :( Hope to see it soon! Awesome video as always!
Great video, keep going .I amfull of curiosity
Thank you the the education sense!
Great video. Thanks.
OMG! IT HAS BEEN SO LONG!
Big Fan of your channel love your content
Are you engleshman? I'm not, but i'm subscriber of first "Thoisoi" channel, first channel have a 1 000 000 subs.
Sorry for my English

I never wanted to be a chemist until I met you. You are an amazingly knowledgable & smart person. You really put your all into this. Please be careful like you know how. I saw your hand when u try to cut a little corner & rush things.. Take care & God bless.
First like, first view, first comment
Love your videos😍
Thanks for these videos it's so helpful
can i find you articles or doctorate notes
Hi, I have a question when interactions occur frequently in aqueous solutions What kind of reactions?
Thank you my friend
Very nice. 👍
"Not like the video game DOTA." LOL nice play.
I always wait for your videos cuz its so interesting
Great video
Make a video on Lv
Very cool vidzz, Thanks, no heroics or clown acts.... just good natural info
Just fascinating
First time for "I watch your video in 30 mins after it's posted".
Usually when I saw a new video, it has been posted for some hours, or days...
I mean it a monent I want to make a memorial.
I understand you my friend
Thanka uu aa boraaat! Hi 5!
Bhoat hard na bhai
Discovered in 1907? That's crazy. Think how many undiscovered qualities that and other late discovered elements could have.
what's even crazier is having worked out the structure of atoms & most of the elements before airplanes or refrigerators were available
Can u make a really long video where u put all ur elements experiment from 1 to .... in sequence. Thank you for all the information u share
Thank you for the videos. They’re great for people with short attention spans,like mine!...lol.
Interesting!
THEY'RE ALL THE MOST EXPENSIVE
Nah
Sodium hydride
How do Au know?
I love chemistry!!
me neither
lmfao
The only reason i understood chemistry is by your channel..... Thank to very much.....🤗🤗🤗🤗
We need dis in school
Please do video on Bk or Am
I’d love to know where I can buy these different metals! Just a small sample roughly the size of a dice 🎲
What would you do when you find a stable isotope of moscovium?
Nice
... video
I like this video.
Where do you get all these
excellent
this mans going to end every chemistry teachers career
Give me the Gold-Pressed Lutetium, Quark
Rule of Acquisition 240: Time, like lutetium, is a highly limited commodity.
Sir please tell me what is hardness of lutetium
thq love u from india bro
You call that boring? It's so much richer than all the other sugar-coated dumbed-down materials that other explain-away teachers on RUclips seem to have.
is it poisonous? what are effects if you drink lutecium chloride?
What are you going to do when you do all of the elements?
Who needs all the science stuff, we all only watch your video for the cat bits at the end ;-)
I miss the owl sounds that use to be in the beginning!
4:44 what is a neutron trap?
It is interesting watching the single, bright pixels created by radiation hitting the CCD elements. Minute 03:00
How strong is it compared to other metals? Is it softer like gold or galium, or is more of a harder metal like palladium or osmium
The hardest lanthanide metal is still less harder than softest transition metals
Can you make a video on ununpentium
Can you make a video about FRANCIUM
Please how can I know the metal is lutetuim
Make a video on flourine
Please please make a video about tungsten
Please make a video on koilin
Explain why iron is the most stable element. Great Channel
It is iron 56 isotope, which to be fair makes up most iron. It is the most stable element because the number of protons and neutrons is just right for it to hold together (essentially) perfectly.
Can you make a video about americium next?
You can find Am-241 in some smoke alarms.
Then build a cloud chamber, then you can see some radiation.
Aiden then acuator Brunswick
I spell lutetium like lu te tium.
Thoisoi spell lutissium correctly.
Now I need more education about chemistry elements name.
Please tell the name of anti iron chemical!
Make one on graphene please
这个视频非常棒
吃萝卜烤地瓜 agreed !!! :-)))
3:22 And the Hulk is born🤩
You really should collect the powder under that grinder and make an alloy. You have grinded so many exotic metals. Who knows what would happen. Find out for me will ya?
Even if you created the greatest material ever you would not be able to reproduce it because you dont know the ratios.
Thoisoliuminite well something thoisoite? Thoisoilite? You better do thr naming of ur possible meta material.
Brother, is it anti iron?
Incrível!
Can you do a review about infinity stone

I am asking about astatime everytime but u r not doing it
Is it heavy?
WOW nice glow :D
*_WHEN ARE YOU GONNA DO A VIDEO ON BITCOIN???_*
@@burrbonus *_THATS WHAT I'M TRYING TO FIND OUT_*
OMG this can be used to make high temperature superconductors WHICH COMPANIES MINE THIS??
Thoisoi, do you play Dota?
Funny or perhaps pathetic it may sound but every time there is a new metal on RUclips though i remember well my days at high school still it feels like everyday there is a new discovery concerning metals that used to be totally unknown to mankind and womankind.
Please make a actinoids playlist in ur channel 🙏🙏🙏
His accent is just amazing
N-doped lutetium hydride is an ambient superconductor at 1GPa with a 1/3 success rate, going from blue to pink to red.
could rare earths be created artificially (instead of geological extraction)?
I work in a fertilizer store facility, now I'm scared

This is sense of youtube
It's more like the sense you don't possess to understand why things happen. It's all very simple.

Is this metal sold as a precious metal like silver, gold and platinum?
The lanthanides don't make good precious metals but I'll gladly take any samples you don't want
