Iridium - Periodic Table of Videos

[EvanIridium]

Iridium comes from the Latin word "iridis" meaning rainbow for the different colored solutions it makes.

They didn't mention where the name for Iridium came from.

[meatisdeliciouse]

I wonder if he hase any pollonium 2:10?

[xNickTheBrickx]

I demand a longer video.

please. :)

Iridium is very dense, has the lowest reactivity, & a very high melting point. It's usually found in platinum. My mother has a watch made of platinum, & contains 10% iridium, & has dozens of diamonds on it! It was her grandmothers. My mother wanted to sell it because of financial problems. One guy wanted $250 for it! F*** THAT! I told her to NEVER SELL IT (she took my advice), regardless if it doesn't work! It's one of those things that's so rare, you question it. Iridium is SO RARE & BEAUTIFUL!

[silverleaf81]

Iridium is so damn dense, unfortunately its very rare due to it being found only in meteors...i think.

[InfiniteExistence]

that's some crazy hair

[HaloHamstur]

any chance i can get a spork made of this?

[ezasad]

Ir is also used as an electrode (or part of the top and bottom electrodes) for certain specialized capacitor applications such as ferroelectric memory (FeRAM) capacitors.

[FlashFizz]

Maybe iridium will become the next platinum due to its lack of toxicity and extreme density, rarity and resistance to corrosion.

Although the element is difficult to machine, an iridium coin would have some heft and remain new-looking for millennia (right?).

It is much more common in some types of asteroids and I wonder about the feasibility of mining it in space.

[lorax2013]

Great idea for a series of videos, but after watching a few I see the grad student appears to make some mistakes.  For Iridium he states it is light weight when in fact it is one of the densest elements. For Indium the student said it was toxic to touch which is totally incorrect. I wish they would put a comment overlay on the videos clarifying some of these points, otherwise it is spreading incorrect information.

[Djmankiewicz1]

@lorax2013 Density and weight are not dependent on each other. A sample may be very dense without being heavy. He was referring to the fact that his specific sample was "sponge type". As for the toxicity of Indium, I'll take your word for it, as I'm not at all familiar with it.

[gennaman2bit]

@Djmankiewicz1 lol actually the density is the weight divided by the volume, how can u say they are not dependent on each other?

[Djmankiewicz1]

@gennaman2bit Density is mass divided by volume. Mass and weight are not the same thing.

[gennaman2bit]

@Djmankiewicz1 yeah, language mistake sry. But u can assume weight and mass are directly correlated (in an accelerated environement and excluding Archimedes law)

Correction:

Density is weight / (gAcceleration * volume)

[smeghead666]

I wish I could go to your university :(

[magicicle]

I thought the thumbnail shows a penis...

[TotalNekro]

I have to say Iridium is one of my favorite metals.

[HazMatLabz]

@TotalNekro Same here

[MAJIKVEGGIE]

Most of my fountain pens have had iridium nibs. Why is this?

[liquidoxygen0]

MAJIKVEGGIE: The nibs constantly have ink flowing through them, which often contains some water. Since Iridium is the most corrosion-resistant of all metals, that is used so that the nib never loses its writing ability.

[douro20]

A handful of spark plug manufacturers (NGK was the first) use iridium electrodes in their spark plugs.

[gijzzzdude]

Cause that's the way pen makers like to have it, man.

[juggliac]

how come osmium and iridium, there's no mention of its density?

[periodicvideos]

we made all our videos very quickly and we're now going through updating them one by one with more details, better experiments and extra stories... stay tuned!

[s4m5on]

@periodicvideos the vids must be done its been over year

[mostliberal]

That's what I was thinking. It's the DENSEST of all elements, and it also has the highest melting and boiling points. It's also very special because it makes up most of the KT boundary. The KT boundary is where debris from an asteroid got deposited all over the earth, from the fallout. That asteroid is what finished off the dinosaurs 65 million years ago.

[liquidoxygen0]

mostliberal: Acually, Osmium is the densest element. Carbon has the highest melting point, and Rhenium has the highest boiling point.

[HazMatLabz]

@juggliac Osmium is very slightly more dense actually but there is speculation about this. Though, osmium has a way higher melting point.

[slateflash]

Lightweight? Iridium is second densest next to osmium!

[tomandjj]

what about it's extensive use in satellite phones?

[douro20]

Iridium in that case is the actual name of the product; there is no actual iridium in it. The name comes from the fact that the signal comes from space, and that iridium was first discovered from a meteorite.

[davebestmusic]

No More Crazy Hair!

[cool70200]

hmm, interesting stuff, smart nuggies

[Draxis32]

Yeah, and i cant believe that they forgot to mention that Iridium is the greatest of all metals on density and immunity to corrosion.

He's density is 22650 kg/m³ on IS, if you think that Lead is very dense, you cant even imagine this one, wich is twice as dense as Pb.

That's maybe why he's only found at meteorites, wich could came from a destroyed planet or something, also we know that some vulcans expels iridium, wich could prove that he's so dense, that you can only find it, inside earth.

[AlmightScoop]

I dont believe that they didn't mention the iridium anomaly. Iridium is pretty rare on earth but pretty common in meteorites. There exists a layer of iridium in the same strata that corresponds to the extinction of the dinosaurs. This makes good evidence that a meteor made a contribution to the dinosaurs demise.

[ZenityChenity]

Just randomly saying...The "iridium anomaly" is called the K-T boundary or sometimes called the K-Pg boundary.

[mostliberal]

@AlmightScoop I know, I think I mentioned that in a much earlier comment. There's a layer of iridium everywhere on earth because of that asteroid. A funny story is that when I was 7, me and some friends dug a huge whole in a huge in the sand of our school playground. We found many colored layers of sand, and the deepest, thickest layer was fine red sand (from the Jurassic), but before that, there were white plaster like layers, and a very thin, gritty, black layer of iridium in the middle.

[TheReaverOfDarkness]

@mostliberal Not to burst your bubble, but whoever told you that's what it was probably didn't know what they were talking about. Sand from back then is mostly fused together into sandstone if it hasn't been altered in some other way by now.

[ActionReplayPerson]

@AlmightScoop Also, it is noted that it is a bit harder than diamonds.

[thirdeyewise2]

@AlmightScoop

Did you say Iridium and mass extinction? You might enjoy this video....

@thirdeyewise2 That guy is a fake.

[thirdeyewise2]

@TheReaverOfDarkness

I don't think so. 

[xspartanX3x]

@AlmightScoop Ancient Aliens documentary talked about this season 3 ep1 but I recommend you check out season 1 and work your way up... truly fascinating indeed.

Nooo, what did you do with your hair?!
