Osmium - Periodic Table of Videos

[StephenFiorentini]

Who else noticed the screensaver?

[thutama]

why didn't this mention the haber process?

[DazIOM1140]

How do you get it out of the vile in order to use it for experiments?

[omichron420]

@DazIOM1140 you break the vile?

[DazIOM1140]

@omichron420 but how can you do that when it just reacts with the oxygen?

[dannymarashi]

@DazIOM1140 i dunno about that although if it reacts with oxygen which is part of the air maybe it could've reacted with something else along the way but i think chances of that might be 50-50

[exploremagic23]

Why is it that scientists have the same crazy haircut...

[HazMatLabz]

@johagla elements 105 to 109.

[HazMatLabz]

@johagla almost everything that is transuranic :P

[barkeeperhead]

@EvanBixbite wrong, the element with the highest melting point is tungsten (in europe sometimes:"wolfram") with a meltingpoint of 3410 degrees centigrade.

[hisyamuddinistari]

He is my FAV SCIENTIST! He makes it simple and informative!!

[kdog177]

any one eles hear because of fringe!!!LOL

[Idkkeponer1]

WTF's up with all this 3 and 4 dislikes? why do you three assholes keep watching if you don't like it?

[pauldotp]

@Idkkeponer1 definitely

[mYOzZyKaT]

Donny Osmium

[Jeddie256]

Wow. Great vids. Stumbled upon and I've been stuck on them for an hour. You have a new fan.

[DevilMaster]

Can a material denser than osmium be manufactured?

[1RadicalOne]

Oh, yes. Using an extreme example, the material of which white dwarves and neutron stars (remnants of the cores of dead stars) are much much denser. In the case of neutron stars, many thousands or millions of tonnes per cubic centimeter, if I remember correctly.

[DevilMaster]

@1RadicalOne I am aware of the extreme densities of stellar and degenerate matter, but that is not what I asked. I asked if denser materials can be *manufactured*, which means obtained through laboratory or industrial processes.

P.S.

"Dwarves" is a word invented by Tolkien for The Lord Of The Rings. The current English plural of "dwarf" is "dwarfs", while the Medium English form was "dwarrows" ;-)

[1RadicalOne]

The distinction is an artificial one; all are created by physical, chemical, or nuclear processes, and as such could, in theory, be done in a laboratory of sufficient scale or advancement.

If you mean possible now, I do not know what the limit is, though I suspect it is still above osmium.

More, that is separate from what has actually been done; for example, I suspect something could be obtained by a properly directed nuclear explosion of sufficient size, but such a thing has never been done.

[bushiyo2]

@1RadicalOne Your ignorance makes me sad inside.... :(

[1RadicalOne]

On what matter, specifically, am I ignorant enough to cause you to be "sad inside"?

[frizstyler]

@1RadicalOne wow.so let's say a cubic cetimeter of this substance appeared on our earth's surface...it would move toward the earth,and so would the earth,too.it would penetrate the ground,pulling everything with it,while going for the core...earth would be "blended",forming a new planet ,probably smaller,with this substance as core.hmmmm,this would be an interesting computer simulation,can someone do it and show in youtube?

[SgtMustang]

@frizstyler What the hell are you talking about?

[pietzeekoe]

Isnt this stuff the heaviest stuff in the periodic table.....if so it was worth mensioning

[BGood156]

@pietzeekoe Not the heaviest, but it is the most dense.

[silverleaf81]

Osmium is deadly, because if it does evaporate, it can coat your eyes and blind you.

Also, its very toxic.

[lionotto]

My name is Osman. My favourite element is Osmium.

[osmium083]

Cool

[InterMagicChrome]

What was the compound???

[dunnobutwayne]

mmmh yummy osmium sponge

[neutrillium]

can osmium be mixed with another metal? if so would the alloy become toxic could it be handled

[temporaldisplacement]

To be fair synthisising chemicals/materials sounds just from the outset to be quite laborious and time consuming. / Worthwhile ....but there isn't a nobel prize in synthesis to my knowlage, which might work to its disadvantage. ^.^

[CapPicard]

Introducing the Partridge Family element! And just as dangerous as the TV show! :)

[homousios]

The professor should write a book. It could be called " Meeting of Elements: My adventures in the Periodic Table." I will be a customer as I am sure will also be many of your subscribers

[deaftodd]

why do all professor have crazy hair?

[GlovedFury]

@deaftodd Work and Research First! No time For Hair!!

[Edgebotv4]

@deaftodd

job requirement . phd ....check, field experience... check, wild untamed hair ....check.

[wikichris]

Can you smoke it?

[TheChemlife]

has anyone made osmium dicarbonyl dinitrsyl or used it for anything?

[merchant117]

osmium i love how its sound OSMIUM

[1993gandy]

so basically he just mixed a load of things to get osmium compound lol

[hailholyghost]

Hold on there, at 0:06 he says that Osmium is a platinum group metal, that is NOT CORRECT!

Osmium is definitely in the Iron (Fe) group. Osmium (76) and Platinum (78) are in the same period though, perhaps that's what he meant. Anyhoo, I just saw that no one else mentioned it.

[chumchumthegreat]

@hailholyghost

But Osmium is a platinum group metal, type "platinum group" into wikipedia for more info.

He didn't mean "group" as in the columns of the table, but as the platinum group (again- see wiki- or other more trustworthy encyclopaedia)

[hailholyghost]

They call it "Pt group" b/c the 6 metals (Ru, Rh, Pd, Os, Ir, and platinum) are usually found together in an alloy of one form or another. They should have clarified that in the video.

Thanks much for pointing that out

chumchumthegreat !

[ChronicMist]

finish kindergarden kid. then talk crap

[shiconia]

As the internet hailholyghost, you're doin it wrong.

[KarbineKyle]

Osmium is very interesting... It's a silvery-bluish metal, and I collect minerals, gems, metals, etc. I would like to find a sample. He mentioned it has a strong smell, well "Osme" in Greek means "Smell". In natural abundance, about 42% of it is radioactive and some have extremely long half-lives. I believe it decays by double beta minus decay. It's also the 10th metal to have the highest melting point. It is also the most dense of the natural elements, 2X that of Lead. I want to get a sample!

[chargerfish1]

@KarbineKyle i know it has a very high boiling point, but how does it evaporate easily?

[HazMatLabz]

@chargerfish1 the metal doesn't, it's the osmium tetroxide that evaporates or sublimates rapidly.

[chargerfish1]

@HazMatLabz oh ok

[tooolnut]

Osmium is the densest of elements, or somewhere up there, it should be mentioned.

[HazMatLabz]

@tooolnut it is the densest naturally occuring element. there are denser elements but they are synthetic.

[dowblab]

Why do chemists and scientists in general always have hair groomed like wackos?

[Turok2evil]

@dowblab

i wonder the same thing ..my chem teacher at school has some crazy hair too x]

[LongX49]

lol XD

[uli903]

@PremiumZero lol cabal online is the main reason people see the video

[rroge5]

makes you go blind and thats it?

[BibleBurnr]

if ur blind ur might as well dead.

[sktang333]

isnt osmium green? or is it just that its still in a processing stage?

[RazielKain]

in general the color of "elements" is dictated by the state of oxidation

[hash1212]

great vid again.

osmium tetraoxide is also very important to the usage of electron microscopes. it functions as both a stain and a fixative.

[xCrosSxKnInE]

i thought it was green

[Airsofter1995]

Whats up with all the long comments?

[Coredo]

Dark Black Metal! \m/

[Project107]

Osmium is one of my favourite elements just for its super high density. I know that there has been some debate about whether it is osmium that is the densest or if it is iridium since, I think, in crystal form iridium is slightly denser but I've always liked osmium better. Just recently it was proven than osmium has the highest compressibility of any other element, even carbon. Also and interesting tidbit osmiums name actually comes from the Greek word for odour because of its strong smell.

[Draxis32]

But is it more dense than Iridium or not?

Also answer me, what is this compressibility thing you're talking about, you mean that he can stand high pressure than any other element?

And why does this metals, like iridium and osmium are so strange, they have extreme cutting power, at levels that only non-metal elements have, have smell, and still shines,conduct eletricity and are low reactive like metals?

[Project107]

I think, that osmium is slightly denser than iridium in its naturally occurring state but when both substances are crystallised iridium is the denser. As for the compressibility, that was a mistake on my part. It actually has the highest resistance to compression even when compared to diamond. Anyway, osmium is actually and extremely reactive metal. Its odour comes from it reacting with oxygen. Since it is so reactive it is commonly used to make alloys but it is almost never used by itself.

[Draxis32]

He's reactive?

Lol i though that in the Periodic Table of elements, those who were far from being electropositive and electronegative(of course not counting the noble gases) elements were the elements wich had less reactive as possible.

Such as Iridium, wich only reacts, as far as we have researched, with liquefied salts like NaCl or NaCN.

Does he really reacts in metal(for what i've know its very different for normal ones, it sorta look like non-metal compounds like grafite type) state with O2?

[Draxis32]

Cause im taking the fact that if your far from electronegative ones, and electropositive ones you would be in the middle, and Os an Ir are exactly in the middle of the periodic table(not counting the radioactive elements).

Can you send me, or tell me where i can find better researches about these 2 metals?, im interested in them.And by the way sorry for my bad english i've still not mastered it completely.

[metalbiker1]

It is denser than iridium, it is the most dense element in the table

[ElveeKaye]

Blood-colored compounds would be awesome to make! :D

[slateflash]

Samarium(II) compounds are the same, bt unstable.

[0Sebek0]

blood, just mix potasium tiocianate (KSCN) with ferric chloride (FCl3), to make the complexe FSCN 2+, that is just like blood!

[Rejoyces]

and it might end up killing you too

[joeleatsbk]

not quite lol, its used in high schools

[Draxis32]

KSCN is used in schools?

Who is using that?

Cianide, and cianide substances, are extremely controlled substances even at University labs.

[joeleatsbk]

its used in precipitation reactions to confirm iron III ions i think. In New Zealand lol, All of the chemical we use are so that we cant actually make any potential dangerous compounds

[Draxis32]

Yeah i had metal precipitation reactions also, but the professor didnt allowed us to precipitate Hg+ and Hg2+ or using any Arsenic or Cianide here.

They've sat that this are dangerous compounds, and any dangerous substances that get in contact with humans, by mistake of the students, or if it breaks, or any accident of the kind does happen and the person is contaminated is a hell of a sue against the Professor, the Institute, and anyone involved.

[JebusGeist]

"any accident of the kind does happen and the person is contaminated is a hell of a sue against the Professor, the Institute, and anyone involved."

If it represents a high enough risk I would be very surprised if the students did not have to sign some form of liability waiver before working with the substances.

[myrmecophilous]

We use KSCN at my school too, to make iron thiocyanate. The ion is thiocyanate, not cyanide. I guess the bond between the sulphur and carbon is strong enough that it's unlikely to break and give off cyanide unless someone who knows what they're doing forces it to do so intentionally, somehow.

[Draxis32]

Thiocyanate compounds are level 3 of hazard, it's not a lvl 4(the maximum) as the Hydrogen Cyanide itself, but still pose a threat for the health.

I know that SCN can decompose to non-hazard elements like CO2,N2 and S, like in the "Pharaoh's Snake", where you get a Hg(SCN)2 and burn it down, making a serious of decompose reactions wich are quite fun.

But if the substances are under control, there's no problem at all.

[N539US]

this video was added on my birtday

[CitizenErased2007]

I love these guys, really informative and fun! keep up the great work guys !

[maximusben1]

osmium, the most heavy element in the world. Osmium the size of a football ball, would weight 125kg (i think)

[RavnoUK]

just brillian ^^ jajaja " perhaps im not a very good sintetic chemits" .. forrr sure he is ^^!!

[e1doller]

haha love the ending...translation:i had enough for IR and NMR thats good enough for me,who needs colour

[kag6]

@e1doller techincally if he doesn't know the colour then he wouldn't have run an IR since IR samples are fairly large.. odds are he ran an xray spec or something.
