Ex-jeweller here. Just a small correction on the information regarding rhodium plating for anyone that is interested. We almost never rhodium plate silver (the only time we do, is when specifically asked to by the customer, and they are charged accordingly too) as it would make the pieces prohibitively expensive for the value of the metal. We pretty much exclusively use rhodium plating on white gold alloys to help keep it's lustre, as 14ct w/g alloys and above have a very grey appearance, even when polished. Also, replating a piece is so expensive because we have to remove EVERY trace of rhodium, smoothe and polish the piece, isolate where plating is needed, and then plating it in $1,000(aud)/Lt solution. If any bit of rhodium was missed in the initial removal process, it will cause a cloudy bloom on the piece, and you need to start all over again from step one. And if your solution becomes contaminated in any way...you have to buy a new bottle, as it will just cause flawed platings otherwise.
Rhodium is also used to coat "White Gold" a mixture of pure gold and white metals such as nickel, silver and palladium. It adds to the shiny luster and reduces tendency to scratch.
It's a very satisfying process. I am a jeweler, and i always electro plate white gold rings with rhodium after working on them to bring back that beautiful shine.
He said rhodium is twice the price of gold.and that’s only one of the things he got wrong.you learned nothing.gold is 1tenth the price of rhodium.just for starters
Amazing. Rhodium has tripled in less than 5 years and is recently increasing ~1% per day, and there are still only two videos on youtube dedicated to it that are less than 3 years old. If you are reading this, you are looking at one of those rare 10 bagger opportunities that everyone will talk about in hindsight.
For the hand warmer, the Rh catalyst, along with the other catalytic materia, reacts with the vapor of the fuel. So instead of buring in a flame, it merely reacts with the catalyst to produce minor combustion. Like a catalytic converter where the co1 passes over the catalyst and it's transformed unto c02 as an oxigen is added to the carbon. Much like reacting hydrogen with platinum.
Great content mate, cheers! Honestly I learnt more about elements from you than from my whole school life. When I see your recent ones, I noticed one thing better than old ones. Finally you're using tripods. Appreciate it mate! No more pointless shaky videos. Can't wait for your new vids. If I may have a request, I'd love to see you making videos about latest found elements if possible (113-118)
It´s February 2020 now and Rhodium is 6.5 as expensive as Gold. - 9,500 EUR per ounce vs. 1,430 EUR P.S.: Thanks for your great videos on all the elements. You're really filling a gap.
In the 60s I won 1st place in 5th grade science fair. I got a lapel pin of solid Rhodium for prize. I knew it was special but eventually misplaced it. Damn! Wish I still had it! Edit: I just remembered I won it as a 5th grader against all the grades thru 10th. That's why the prize was so good.
Aa a jeweler, I can say that most sterling silver jewelry isnt coated with Rh, unless it's hallmarked as such or during the creation of agentium silver (has other names in industry) which gives it a higher resistance to corrosion. I'm not sure of the hallmark laws in Russia, but in the US silver has to be hallmarked if It's made of other metals. Such as sterling hallmark (92.5). Rh is typically mixed with gold to make white gold and is hallmarked as such. Love your videos, just wanted to put that out there as a friendly heads up.
I was in the Swarovski store with my girlfriend looking at a pendant with a rhodium flash. My girlfriend asked the clerk what rhodium was and I will never forget her explanation: "Rhodium is like, an element, from like, the periodic table of the elements..."
You rightly remember that silver metal blackens over time by forming sulfur derivatives. The zinc metal reacted with silver sulphide, and the cooks of the old days put the blackened ladles, forks, knives and spoons on a gutter plate and plunged them into the tap. I did it again yesterday and in less than one night the silver metal had found its complexion as a young girl! And as this regenerated electrolytic metal is free of impurities favoring chemical attack, cutlery stays clean for a long time!
4:10 Rhodon (ρόδον) in Greek means rose not pink. This metal has this name because its salts have colors like red or pink roses. But other than this small mistake video is great.
Another use of rhodium is in catalysts made out of rhodium coordination complexes, used to manufacture high-purity acetic acid from methanol and carbon monoxide
I am working with ore. I have had numerous problems trying to melt. I finally got them to melt and decided to put the hard buttons in nitric/water hot to remove any junk metals, copper, iron. I am ok with the nitric/water dissolving my ilver and palladium also. I went to go flatten the buttons before putting in nitric/water and they was very hard but broke into pieces. Now I have a white substance in the bottom from the buttons. I had took a button the other day and put it in AR and got a white in the bottom also. figured it was silver, but now that I have the same looking white in the bottom of nitric/water soak I dont know. As I said all kinds of problems melting to a button. Finally a guy said use a Arc welder with carbon rods, this worked but now I have this white. Normal forge is not hot enough to melt. I dont know what it is. Any idea's?
When I have enough money one day I’m going to design a cabinet with the exact shape of the periodic table and make it able to add new sections for new elements in the future, I’m going to try get a sample of every element in legally allowed to own. That’s my goal
Russia is the second largest producer of rhodium in the world (behind South Africa). Russia is also the second largest producer of platinum and gold. And Russia is the LARGEST producer of palladium and the fourth largest producer of silver. No other country in the world is in the top 5 of all of those five metals, except Russia.
By adding a nuetron in uranium 235 it will release krypton , barium , 3 nuetrons and heat What if we react krypton , barium and 2 nuetrons. Will it become uranium 235?
You missed one important use of rhodium: it is used (together with other platinoids) to make dies for the production of glass fibres, such as those used in fiberglass, rock wool and optical fibres. The hardness even at high temperatures and chemical inertia of platinoids are what makes them ideal - if very expensive - for this purpose.
Did not know rhodium was this rare thus discovered on earth what can do that platinum cannot. Too brittle naturally coats silver? or added? and palladium as platinum already do this catalytic converters, too rare to make sense for uses that we can already get through the other 5 platinum group elements. I would like to see (learn) what it is doing or not compared at the same time as the other 5 elements. Thank you, you and this channel make me learn/think and that is not an easy task. Lance & Patrick.
He did mention that it catalyses certain oxides of nitrogen; this is why it is widely used (in tiny quantities) in exhaust catalytic converters on cars. They platinum group metals are similar, but not the same.
Is that true that rhodium is the only element that forms Rh(quad bond)Rh? And the 4 the bond is called Delta bond? And that blob of Rh is it in it's elemental state or like a metal lattice? Help anyways, gud video dude
Nice when you have the lab set up, funds, and most importantly the knowledge. Filming reactions is not easy. The risks, exposure, and effort would intimidate all but the most dedicated. This is not a university supported thing here. Some people just like sharing knowledge, exposing hungry minds to the real world of science. Compare these videos to the religitard ramblings and assertions coming from a money grubbing minister making threats to those who don't send him money. Большое спасибо!
I saw a "Mission Impossible" episode back in the '60s where the plot was smuggling Platinum in shape and quantity of AUTO FENDERS! IM team "discovered" the plot by pointing out to a border guard that the 'fender' bent as easily as 'butter'...
I was 17 in 2003 and I just wished I could learn as much in school back then like I am learning right now.. might have influenced me more to be a chemist.
If you are a brain dead peanut and splash fuel around your engine bay or under your car at the exhaust then yes the heat in the cat converter/mufflers/pipes/headers could cause the fuel to combust
If anyone paid attention to the list at 0:49 you would see that gold is actually less abundant than platinum. We have just been mining it so much longer and that's why we have more. I had to mention that, as the Platinum guild puts out insane lies about how Platinum is 30x more rare than gold...false. palladium is rarer than both of them, but rareness in and of itself doesn't make something better.
Please do element 79 - Au Gold. I have been waiting for over years! The metal which is precious, lustrous, expensive, and awesome! The color of gold is what separates it from other precious metals! Gold is the symbol of the Gods!

It's because it's used in making force fields for military application. That's why it's value is going up lol

Learnt more about rhodium than from any book. Great work, love your videos!

U were so right
Plating Rh on silver, defeats the disinfecting properties of the silver
you don't really need your accesories to have disinfecting properties do you
In such case must better use 999 Silver in jewelry.
copper is more disinfecting, copper silver alloy (common) should work fine too
@@GMODISM Copper is also often an allergen
Googled it and its actually quite a rare allergy. I guess its a genetic thing since my sister and I both have it.
I've learned more from your channel than 4 years of college chemistry!!! Thank you 🙏
Your videos are the best. Thank you for making all of us a little bit smarter.

That was quite informative, thanks for sharing. We overlook a lot of things in our daily lives without realizing their importance.
If this was melted & then moulded would it be good for small jewelry like a ring?
Love the hand-warmer information!
Another great video! Thanks Thoisoi!
How rare it is they sure do use it in a lot of stuff
Please do a video on fluorine.

I've been walking around with freezing hands all these years, not knowing about these incredible catalytic hand warmers!? :o
What would looks like that the ruthenium, rhenium, osmium, iridium metal pellets hit by a hammer? How brittle are they compared to rhodium?
Just gained a new subscriber 😊

I love the way you say “Iridium”
Explain why iron is the most stable element you are the best of explaining the elements
Iron 56 has a very strong attraction between the atom's protons and neutrons, due to the strong nuclear force.
How can find out its oer ?
Nicely put and good way to understand keep videos going
When I have enough money one day I’m going to design a cabinet with the exact shape of the periodic table and make it able to add new sections for new elements in the future, I’m going to try get a sample of every element in legally allowed to own. That’s my goal
Very good video and answered all my questions
may I ask, what chemicals do I dissolve to dissolve metal Rhodium? Thank you!
What is song in background? It is very nice
thats why its my favourite element! many applications, especially catalytic, but not many people know about it.

No, it is a catalyst in the process.

It looked like the rhodium got red hot while being hammered
No, from my side, it was deliberately heated to make it softer.
Will only get a bit warmer and as it breaks, itt releases heat. If it was platinum and took 50 good hits it would be a bit warm too.
Is that true that rhodium is the only element that forms Rh(quad bond)Rh? And the 4 the bond is called Delta bond?

Me: "Okay... I'm listening. You have my full attention."
I have a piece of metal that been hand formed...believing it to be rhodium,can u help identify it
This was a good one. Good job!
