So today I will tell you about the most rare metal on Earth - iridium.
Iridium is a transitional metal, which is located in the middle of the periodic table, below rhodium. If we take a look at the prevalence of all elements in the earth's crust, Iridium holds the last place, that is a billion atoms of all that there is and only one atom of iridium. This metal is 40 times rarer than gold.
In much higher concentrations iridium is found in meteorites and also in the depths of the Earth, in magma. Interestingly enough, in the layers of rock sediments, though more precisely in the formation of clay, that is aged about 66 million years there were found high concentrations of iridium and this can indicate the collision of Earth with a huge meteorite in the past, which in theory was the cause of the death of the dinosaurs. In it’s appearance iridium is a shiny metal that does not oxidize in air.
This metal has almost the highest density of all metals, just 0.12% lower than that of osmium - the most dense metal.
In this tiny tiny metal droplet, which is of the size of a match head, we have 1 gram of iridium. To help you understand how high is the density of iridium, I will show other metals with the same mass for comparison.
Lead, copper, gallium, zinc, magnesium, and the lightest metal - lithium.
The volumes of the first and last metal differ by about 30 times, although their mass is the same. Iridium is also a very hard metal that is firmer than the solid steel in 1.5 (one and a half) times. Iridium, in addition to its rarity is even the most stable metal that does not oxidize in air up to 2000 degrees, and is not soluble in either acid or aqua regia. Iridium can only react with the fluorine at temperatures of about 600 degrees.
Unfortunately, due to the low activity of iridium, I cannot conduct any chemical experiments or have quality reactions with it.
The only thing that I can do is make a fine powder of iridium and set it on fire in the air, but as you can see, in this case iridium dust is burning quite slowly and also requires dispersing it in the air. For the first time on youtube, you can observe a burning iridium. Also, due to the low activity of iridium, the metal does not tarnish in air, even when heated to above 1,000 degrees. The only thing that the drop of iridium got covered with is a partially evaporated ceramic layer, the one that the forceps are made from. Iridium compounds are can be either brown or yellow, such as the complex of Vasca, which is used as a catalyst in organic chemistry.
By the way, Iridium is the only element that can give away 9 electrons and form compounds with +9 (plus nine) oxidation state.
Iridium now finds many uses in science and technology.
In most cases, we will probably find iridium in spark plugs for vehicles, due to the high stability of iridium to oxidation under the influence of electric discharge.
Pure iridium is used for making crucibles for growing single crystals, foil for making non-amalgam cathodes, as well as as a part of the highly resistant to corrosion alloys.
The first standard of mass of one kilogram was created in 1889 using an alloy composition of 90% platinum and 10% iridium and is called the International Prototype Kilogram, it is still kept in the Paris Chamber of Weights and Measures.

Guys,
if you are having difficulty understanding him... He has provided subtitles in more than 5 different languages.... So stop making fun of his accent and thank him for sharing his knowledge with us all.
By the way bro great video keep it up! 👏👏
If u not understand his language turn on the captions option in you tube settings for lyrics
Fuck the awkward accents
Rahul Jadhav Everyone likes his accent
Well I can understand him 100% clearly
It's not his knowledge, its wikipedia's knowledge.
I like this scientist's accent. We are very fortunate to have this highly educated individual on our planet. Thank you, and continued success on your channel!
What accent is it?
@@pinktourmaline4930 german or russian or
@@pinktourmaline4930 Russian
Most will excoriate him while simultaneously naming the kardashian sisters.
Is is a german accent
"Here we have THE most rare metal on earth"
"Lets make it a powder and set it on fire"
Naturally.
It's a spark test, a way to test what different metals are. Good information.
Halfway I know it's a joke... but all d way I'm laughing! 😂
I have this metal in my hands
It's not rare if it's in our spark plugs
Cood

thankyou skull cavern 100++
Wow that's is my dream right now.
@@NathanRotic He is rich!
i have a metal mix of iridium
Thought I had a palladium plated antique gold bowtie. It tried to sell it at a cash for gold place they used the gun on it and showed Iridium and copper they said. The Iridium is thick I'd estimate about a gram or 2. I need to figure out a way to sell this thing they didn't offer to buy it.
Everybody needs Albert Einstein in their subscriptions.
no I don't
Albert Einstein yea I do
Heck yes! You're right!
lol
Always needed that
“Rarest metal on earth”

He is really making very knowledgeable video, Appreciate him
Ok
um osmium is rarer
Absolutely
We take care of him in *MOTHER RUSSIA*
@@wibu5616 to vze
I love this channel. It's almost like a meditation for me like so many scientific channels. It allows my mind to focus on details and gives me rest. When I watch these videos I'm not worried about war or famine or betrayal. I'm really grateful you make these videos
All my farm tools are made of Iridium. :)
erm...No.
And my sprinklers too ;D
Starbound?
***** Oh! thats right, i never made into iridium in stardew valley, but my save still there.
Richard Forester and im a bucket of sardines
and dont forget, safety is number one priority!
Bared 😂
I saw Iridium 192 in the title picture and was disappointed to not have it mentioned in the video.
Iridium 192 is a great radiation source with 1 TBq/g at saturation, used for non destructive testing for example.
You are absolutely right.
@@analogaudio285 Correct, you will also appreciate the half life of Iridium 192 Isotope to be (approx 72 days).
Smells like cinnamon when you crank it out! 😂
I have what I thought was a maybe palladium plated gold antique bow. Took it to a cash for gold place as I could see a hard to see 1 but distinctive 4 and a K after, under the thick coat of what they told me was Iridium. They hit it with a gun and said it's Reading Iridium and copper which also looks like gold in a tiny worn spot. Could the Iridium mess with the reading being radioactive or maybe to thick to penetrate? I'd like to sell this thing to have extra holiday money. I got in a pile of different mostly fake but found alot of gold and gems in this bag for 50 cents.
@@dannysllrs if they analyse it with a xrf it could be a problem since this method is based on x-ray. You could get it analysed with a spectrometer (it uses a spark and analyses the light)
I had no problems understanding him.
And now I know a lot more about a metal I only knew a little about before. Thanks for the videos! :)
Love your videos. One of the best chemistry channels around. 🙌
"zat eez uh-bee-lun a-tums uv all-za-za iz only wan a-tum uv eh-rid-yum"
You can help me with english subtitles.
That's not nice.
I'm not trying to be mean, but I really couldn't help with English subtitles because I could not understand a good 30% of what you said. I get it, English is not your first language and I do not hold that against you. I still managed to hear enough to learn a great deal more about Iridium than I previously knew, so I thank you for that.
A full video script is in the video description.
Don't make fun of Russians or you will be Putin jail !
:o)
Learning stuff that i never knew through your videos. Thank you very much!
Hey! Your vids are really educational and I'm really enjoying to watch them specially because I'm writing some stories about some characters I created and your vids really help ahah so if iridium is the densest metal, does that mean it's the most resistant as well?
I don't know why, but somehow the thick Slavic accent adds to the impact of this film, even though facts are facts in any language... for some reason, "Slav = authority on chemistry" in my brain... it's nonsensical of course, but a Mexican/American accent would not fit as well.
The periodic table was invented by a Russian, so you do have a point.
worth a try to get an indian computer call center guy to read the transcript of that video
It reminds me of period scientific films.
"For the first time on youtube, you can observe..."
This series of videos is epic stuff and rarer than the materials it experiments with!
He checked every video, this is first time you can observe whatever incomprehensible thing he said
Thank you for an excellent and professional video. And the kitty at the end is really cute!😺
Man you work... seriously thanks you to exist and you knowledge. For people who love chemistry and want to see what we learn you channel is perfect

defiantly, some cold war mad scientist shit
russian accent but using german words... what an hybrid :D
In Russia accent speaks you.
In Reversal Russia, jokes make YOU!
That’s what I was saying , also subscribed , idk it’s also soothing
Oh my god, I loved the adorable cat at the end!
I am actually extremely interested in iridium because I am looking to machine it. It was really cool and educational to see these things physically done to the metal. Thank you for making this video!
I have 2 kilos end 300 handred grams of iridio here in chihuahua mexico how much you pay fore gram cel 6391909073
Did it work ?
Pls answer
I have very much
What am I doing with my life watching this video?
xWafflezGames Ha ha
same here -.-

I’m doing a element project in my fith grade class!!! I got iridium and antimony thanks for the help!!!
The whole periodic table collection of elements examples costs like $1,5K with shipping included holy crap
sound cheap
HungQDang You only get a gram or few per each element; but again that might be very cheap compared to what else is out there
*****
I know it is a gram each, but consider many of them are more expensive than gold and packaging all of them take some works.
Yes, more expensive and rarer and I could bet some of them pretty difficult to pack due to the fact that they're extremely reactive and might easily change if in touch with the oxygen from the air or something like that
Link please me will buy
I'm surprised there's no borderlands comments on here.
spiritfinder321 i guess you mixed iridium with eridium
lol I just made one..... yes I know they're spelled different :P
spiritfinder321 lol hun
My main interest in iridium is that it was for many decades used as the tipping material on the point of most quality fountain pen nibs. The nibs were either made of 14 to 18 kt. gold or steel, and the point would be dipped in a VERRRY tiny drop of molten iridium to create a round ball at the point. The ball was then split like the rest of the nib so that ink would flow through it, and polished to glide smoothly over paper. Being an extremely hard metal, it was more durable than a point made of gold or most types of steel. Pilot of Japan was the last pen company to use real iridium as tipping material. They actually bought the world's last iridium mine to make sure they would have a supplier.
I have such a pen. Also used for the bearings in precision compass sets. My dad had one and I loved drawing with it.
Great video, I enjoyed this one, great information.
We say ''rarest'' and not ''most rare''.
True bro.
FivePCgames I bet he speaks better English than you speak Russian.
Dick Fitzwell Я не думаю, что так.
Who are "we"? Speak for yourself blyat.
It is common for people to say (or write) "Most well known" instead of "best known." I don't know why.
1:54 This is a great way of presenting it !
"Which is located in Ze medium of the periodic table".
Gotta love the "Ze"
I love the fact that most of his video titles give a one liner trivia fact that might be asked in Who Wants to be a Millionaire
The narrator would make a great James Bond villain
That Russian Accent is the king.
Vaska @3:01 sounds just like Vodka.
Is it Russian or German?
Russian, you can tell when he pronounces the "h" sound as a soft "ch" as in "chemotherapy"
Gemans can speak a proper "H", long vowels like "aaaw" and do not roll the "R" like that.
Indeed, both have trouble with "th" in common.
ZambaZzee I’ve been noticing the sudden increase of Russian videos or Russian-narrated videos on here. It’s like I’m watching VKontakte (Russian FB)!
And not forgetting the Iridium Throne from the Traveller RPG
Do Rhodium next!
Great educational video
Still cheaper than cocaine...
$ 80? Here in Germany 1 gramm of cocaine is on average $73 (69 €). And You can have way more fun with cocaine.
B20C0 Oh, ein Deutscher :O
Zoid Burg lol , addicted much 😂😂
I'm in North Carolina about 45 a gram here
Nice.. I like how this went down a whole different road..
please make these videos slower and much longer - add in all the information , how they were found , where they are found and so much more ! I know I can read this stuff , but I love the videos , they're so interesting ! SO - MORE , MUCH MORE PLEASE !
I want this guy doing the voice overs for EVERYTHING!
There are so many other science channels on TH-cam but I like yours the most. Largely because of the way you make an effort to speak in a language that isn't your first language. When I was little I used to think the British accent was funny. Then I got used to it. Learned about the American accent and got used to it too. You speak so correctly (grammatically) it's like a new way of speaking English. I'm loving it. 😄😄
There are not enough decent chemistry based channels. my son(9) loves watching with me, he particularly likes the video on cesium. cheers! keep it up. also please do selenium/tellurium.
if it's rarer than gold does that mean it has more cash value?
Rarity and value aren't always linked. If it's rare but of no use either in industry, science or in an artifact such as jewelry, who would pay for it? The video stated it's worth $80/gram. There are 28.35 grams/ounce. So Iridium is worth $2268 an ounce. It looks like the current value of gold is $1166 per ounce.
I had just finished editing my comment to you to include the qualifier that rarity and value aren't always linked. In the case of a dinosaur bone, it has a scientific value and for some collectors or museums with an archeological bent, value as a show piece.
I dug up a rock in my backyard. It is unique in that it is the only one from my yard, so it is extremely rare. Anyone want to buy it?
Gregory Parrott haha I read the value per ounce & deleted my comment. It's worth more than gold. Your unique rock analogy is very vague. It's not iridium or gold. But you know where I'm getting at without being circuitous & sarcastic. Iridium has more value than gold. 😎👍
The rock analogy is admittedly vague. I was trying to think of something very rare but had no correlating value. My first thought was 'dinosaur dung', but then realized that might be very valuable to archeologists, biologists, etc. As they say, 'value is in the eye of the beholder.'
Very true. Dinosaur dung is on my bucket list. Just so you know. 👍
Thank you Thoisoi2. I like very much your videos. I have listened many. Actualll,y learned many things I did not in Chemistry school.
Até que enfim achei um vídeo desse canal ótimo com legendas em português...Devia ter aprendido inglês
Jesus... no wonder spark plugs cost a fortune
Rhenium and iridium are amazing metals. Rhenium is trading at about 1.5 * silver. Yet it's indispensable and probably thousands of times rarer
Iridium : i am the rarest element on earth
Astatine : hold my 4 grams on the earths crust
Thank you so much... For the best knowledge... ;)
Cool video! Keep up the good work :D
can you do this video again sober?
Funniest comment I've see all day!
Thanks for sharing. Very Interesting, I subscribed.
Again, very cool! Learned something again!
"Iridium can only react with flourine"
-proceeds to burn it in oxygen.
I use iridium plugs in my bike. They cost about five times as much as ordinary plugs but they last forever..
It's up to US$275/gram on Luciteria and sold out. Platinum group metals skyrocketed all last year.
valuable information, thanks for such great effort and dedication, maybe add in your videos how to obtain, congratulations.
Haiti is one of the countries in this world that has mountains of iridium...What a special country that has endured the wost.!
@Marie Bigaud because they have
No technology for mining iridum
It's funny because I was reading an article that they are using Iridium to treat cancer imagine Haiti the poorest country could become one of the richest countries..
I dont think so .usa will burn us alive to take all our iridium .why they not ask us to buy it at the right price
your price is irrelevant.
Haiti has iridium. Ok.
Can I establish a mining corporation there and give them jobs wile mining it? no? So whats the point?
Funny how rarity isn't actually what makes jewelry cost so much. It's an unethical person CLAIMING that it's extremely rare and setting their own prices. If rarity was it, iridium's cost would be out the rufe!
What's a "rufe?"
@@al_bal_ roof. Don't be obsessed with grammar
@@meghanachauhan9380 Don't make assumptions. It's "spelling," by the way. Not "grammar."
Nah rarity is definitely the key factor along with usefulness. This metal is extremely rare but also very useless.
@@hakatapawa7115 what is the use of gold btw except wearing it on ur neck?
yo you ever think of doing asmr? your voice is so soothing, and you provide such concrete and fascinating info.:)
We would use iridium to xray welds for inspection. Was so cool to know this existed. Also would use colbolt but not very often. Like who knew radiation would bombard the film around the weld and once you develop the film it gives you a picture of the Weld and will show you any discontinuity in weld. Still find this stuff so fascinating.
I love watching this kind of stuff
i do not have any words for your channel other than that its extremely original
lol. Accurate .
Another women who uses her body to beg for attention.
Let you’re work speak for itself
@@timscoviac that's very rude sir... I didn't insult anyone.
Could you make a proper sword out of iridium? If yes, would it easily shatter upon impact because of it's high density?
Thank you interesting video as always. Finally ordered a little piece of pure Iridium to add to my metals collection ;) my favourite along with Titanium, Molybdenum and Tungsten ;)
Nice information. Great efforts. Thanks for spreading knowledge.
Your accent sounds more rarer than the metal.
By the way, it was a great video!

No. You are an idiot
Maybe the iridium you were talking about is a name of a product, but not made as a iridium.
Many do
is the same iridum but have 0.00000000000000000000_ milligrams per spark plug
Jim V You are lucky!
Rarest, dude. Rarest.
Thanks for the experiment on rarest metal helpful for students
Astatine is rarer
The world's second largest deposit of Iridium is in Haiti. USA companies have profited handsomely from the destabilization of Haiti because they have been able to mine there and keep profits.
I'm not a native english speaker, but I understand him better then most of the native speakers.
Very good channel, keep it up! I hope you don't give a shit to these idiots. I would like to hear them speaking a non-germanic language...
Dávid Horváth agreed. Hungarian is a challenging language
haha yes
lol this accent is hilarious
GREAT SUCCESS!
borat pls
Like a Polish Microsoft Sam.
If u had the same accent as him,u might not think that his accent is funny and u might think ur current accent is funny
I bet you don't speak ANY foreign language.
Splendid video bro,
Continue the streak of splendid explanation forever
Regards.
The collision of the Earth with a meteorite corresponds to the formation of the Moon, and extinction of dinosaurs. Congratulations for the video! It is very nicely done.
