Xenon - Periodic Table of Videos

[TerminvsEst]

@periodicvideos

I'm sure you know that you can inhale xenon to get a really deep voice(much like sulfur hexafluoride). The opposite of helium of course. That would have been a nice inclusion for this video, Pete talking with a xenon voice, much like he did with helium in the helium video.

[peonatre]

@TerminvsEst

There is a reason Xenon is being used as an experimental anesthetic. Xenon can diffuse across the blood- brain barrier. People have come close to dieing from the inhalation effects. They may have died I do not know about that.

That is why they probably did not do that experiment.

[Oafing]

@TerminvsEst On top of peonatre's comment xenon is quite expensive, the balloon had £40 of the stuff in it.

[siderespector]

That guy with the balloons is cheating! He dropped the "xenon" balloon before the air balloon so I suspect an evil conspiracy to cover up that there is no such thing as "xenon". 

[imKrabby]

@siderespector funny guy

[glitterstargal]

@Quintinohthree But the air inside the balloon has a higher density than the surrounding air. (Pressure in the balloon is higher than atmospheric pressure)

Since density is a function of mass and volume, density should not be affecting the acceleration.

I'm guessing that the balloon with air faces more air resistance due to its larger size which causes it to fall slower.

tl;dr different aerodynamics I think.

[arunkumarvikram]

I read in school that irrespective of the mass the acceleration due to gravity is the same for all objects. I am not able to understand why the xenon balloon is falling faster than than the air balloon.

PS:I know this is really a dumb question

[Quintinohthree]

@arunkumarvikram

It's all to do with buoyancy. The bouyancy is equal to the weight of the displaced fluid, in this case the air, while the weight is equivalent to the mass. In the case of the air balloon we can disregard the air inside the balloon because it has an equal density to the surrounding air leaving only the mass of the balloon to be considered. With xenon this is not the case and we must consider the extra density contributing to the weight while the bouyancy is equal.

[StephenFiorentini]

Not that it would do you any good, but if you were to inhale a small amount of xenon, would the pitch of your voice get lower?

[TheGCoast]

Awesome.

[Keletho]

I like how they cut the scenes so randomly and abruptly

[Benivator2]

Sorry for my lack of depth and intrest but HOLY FUCKITY FUCK YOUR FUCKING HAIR IS FUCKED !

[Mrbeahz1]

40 pounds - British sterling that is.

[DementedDogStudios3]

40 pounds worth of Xenon?

I would imagine that it would sink faster than that.

Rip professor

[Hewpie]

I'd love to hear more about tetraxenon gold which I understand is a real compound which has actually been made. Can Professor Poliakoff shed any light on this mysterious substance? That would be brilliant!

[blueduderanch]

can you show a balloon filled with air floating on ethanol and a balloon filled with xenon and see the comparison?

[zearfox]

Correct me if I'm wrong, but when Pete dropped those balloons the density of Xenon should have nothing to do with the difference in the rate it falls as the air balloon, right? Objects fall at the same rate regardless of mass, the fact that the air balloon was bigger, thus having more air resistance would be the reason it fell slower.

[jaydaintith]

@zearfox urm not really.. if certain gasses are heavier than oxygen they will fall (xenon, argon... etc) however if they are lighter than air they will rise (helium, hydrogen etc) mass has everything to do with the velocity of the object... however i can definately see where you are coming from with the air resistance.. I am sure it will have some sort off effect.. Just not enought to make a difference..

[nsaisamrit]

THE BEST  teacher of the periodic table

[Alubrab]

Why doesnt he breathes it ??

Xenon, very heavy, very boring :D



[jocopman]

@Alubrab well it would be the same thing as helium but in reverse his voice would get lower and slower for a bit kind of like adam savage (mythbusters) after inhaling sulfer hexaflouride

[ZuKahta]

sinking quickly? physics is angry.

[theyolkwebshow]

What is the solid left behind in that apparatus? He never specified.

[DevilMaster]

@theyolkwebshow Xenon hexafluoroplatinate.

[assassin4than]

Isn't the blown up balloon comprised of CO2 rather than "air". We don't exhale air do we?

[NATIK001]

@assassin4than We exhale "air" too. Air is just a mixture of many gasses of which Oxygen and CO2 only make up around 22% together , only a small portion of the oxygen in the air you breathe in are actually turned into CO2 so the stuff you exhale is still air, just with a much higher concentration of CO2 than the air you inhaled.

[ARHBritain]

Intriguing

[BubbaHoggit]

I don't agree. I think it floated.

[pooppeeyoupants]

@BubbaHoggit it is too heavy to float. It floats in normal form, but once it teams up with a balloon's wiegnt, it sinks. You could try it with radon, and it should sink horribly like a rock... only if you can GET radon...

[BubbaHoggit]

@pooppeeyoupants That was sardonicism...

[ultrakool]

you see what that wild-haired einstein started. enough with the kooky scientist hair, already

[migkillertwo]

no one ever remembers the grad students

[joe48904890]

I am a student of Poliakoff at Nottingham :D

[japanesepoptart]

I've heard xenon has an anesthetic/analgesic (IDK which) when breathed. how could this be though if it is so chemically inert?

[cuntylishus]

Forty quid per balloon!? Christ, I hope the ESPRC don't see this. Fantastic use of your research budget. ;) Great vid.

[Valce]

I like the balloon guy, he's fun X)

[MrTygaBurger]

he looks like Mort from family guy

[SuperRuckaali]

40 pounds in money or 40 lbs

[lXlNismo11lXl]

@SuperRuckaali Money. The Balloon Would Burst With 40lbs Of Weight. xD

[Sporkinator4]

1:00 looks like bongs.

[LOREepic]

Xenon hexaCHUCKNORRIS! Lolololololol

[rsp196607]

xenon hexafluoride

[frankjohnson123]

"So, there's about 40 pounds worth of Xenon in this balloon."

I totally misinterpreted that at first XD

[RRRohanRules]

I HAVE THAT MUG!!!!! 1:46

Ah crap and I just updated my HID XENON from 35Watt to 55Watt.

[Busterlanger1]

What can you tell me about Xenon Trioxide?

[555jk8]

mountain dew is the best drink ever!!

[donovanshanegreen]

@Wyatt7211 still kinda funny

[donovanshanegreen]

"this type of lamp is used on tanks..that is military tanks" LMAO like theres such thing as a commercial tank

[geeupson]

@donovanshanegreen a tank can be used to describe a container aswell, such as a tank of H2SO4 which are commonly found in titanium oxide plants etc etc.

[donperry1]

@donovanshanegreen could be a water tank idiot. Or a gas tank

[BibleBurnr]

people that enjoy these videos for the hear rather than the content are stupid

[alecmattu]

this is funney

[tooskool4cool]

it was at about 3:23 when i finally asked myself : "why am i watching this?"

[CrazyforDarkness]

make a video of platinum hexafloride please

[bd2528]

damn you look like ?

[opiumgland]

3:46 Galileo was wrong!

[megaelliott]

@opiumgland Is that a joke, or are you just stupid?

[opiumgland]

@megaelliott joke of course!

(thnx 4 asking b4 flaming btw)

[captwasabi]

Ok. Quick questions about the falling balloons @ 3:46. Shouldn't they have fallen at the same rate? I'm always confused by this. I thought that the rate at which an object falls is constant regardless of it's density.

[DarksporkLeader]

@captwasabi Ah yes. Galileo's famous experiment. That holds true when the objects are in a vacuum. In a fluid, (gases are fluid) objects with a density roughly equal to that of the fluid sink more slowly because of buoyancy. An object with a nearly equal density sinks very slowly, and an object with a lower density than the fluid around it floats.

In short, it's because of the force of buoyancy, which is negligible for most solids in air.

[NebulaShark]

I love and hate Xenon LOL. It's a cool element, but It was one of the reasons why I failed a test in a chem course (we had to determine the structure of Xenon Trioxide, but I totally blanked out). I lost a lot of points because I drew single bonds instead of double bonds. -_-'

[MrMahirh]

aluminum glass ? he must be a millionare to buy it

[TheOne1eno]

WTF i block you so why do you come up in my recommended for you list

[NA3CL31]

I wonder if my chem teacher knows about these videos.

[douro20]

Those xenon short-arc lamps are very dangerous; they are filled with xenon pressurized to some fifteen to twenty atmospheres and they can explode quite forcefully as a result if not handled properly; there are many stories of people who nearly lost their hands from exploding cinema projector lamps.

[DarksporkLeader]

@douro20 Bulbs for IMAX projectors are even worse. The bulbs are two feet wide, weigh ten pounds, and are as bright as the sun. Projectionists must wear bomb suits when changing them, as they can explode with roughly the force of a hand grenade if mishandled.

[masacatior]

i want to see neil barlett's experiment... Xenon compound *_*

[kanjitard]

Ever heard about a guy named Galilei?

[Scrap5000]

3:25 Wives never understand genius, do they?!

[UncleKennybobs]

My first born child is called Xenon.

[douro20]

@UncleKennybobs

What an odd name; it means "stranger" in Greek.

[mpwelk]

I would love to be his student.

[MegaZoneEXE]

loves these videos!

5:33 i thought is said "University of "NOTHINGham" X_X

[uut0]

how can you make things so cold that air liquifies?

[gomunkul]

it is possible to make a liquid from a gas by using pressure !

like the liquid gas u can find in butane balloons for cooking.

[uut0]

i kno you can make it liquid by using pressure. but using pressure to liquify it makes it hotter not colder

[umloginqualquer]

To make really cold stuff, like liquid Helium, you need ot use all chilling and pressurizing techniques available. So you may increase the pressure of a gas while chilling it until you get the greatest pressure possible at the lowest temperature. Then you just expand this gas, making it run even cooler. You could do this with nitrogen and then use it to cool helium as cold as you can, then you just do the same to helium to keep it liquid.

[twizlrsizlr]

0:57 bongs

[kingx989]

@twizlrsizlr haha good 1

[Lavabug]

My Inorganic Chemistry textbook says Xenon was first made to react with PtCl6 instead of PtF6. Is that an error? Or can it also react with the chlorine compound, even if its less oxidant?

[mgdurandolo]

Xe also makes a great anaesthetic, the patient falls asleep and wakes up very quickly when breathing Xenon, and being inert Xe causes no toxicity. Just too expensive for practical use. The mechanism of its anaesthetic properties is probably in making the cell membranes of neurons more liquid (less viscous) which inhibits neurotransmission.

[pooten0]

That dude needs a serious hair cut and needs to get laid fast

[Cream147player]

People like you make me ashamed to be a human

[pooten0]

I'm not talkin about the scientist dumbass

[calypsobikes]

lol

[ShervinGetOffMee]

xenon is 2.5x the density of iron... does that mean a ballon of xenon is 2.5x heavier than a balloon of iron?

[thespurginator]

if the xenon was solid, yes.

[ShervinGetOffMee]

why? it has to be a solid to be heavyer?

[thespurginator]

solids have a more dense molecular structure. while each atom of xenon gas weighs 2.5x that of an atom of iron, the molecules in a gas are approximately 20-40 angstroms apart. whereas in a solid, they are closer to 2-3 angstroms.

when gases condense to liquids, the degree of freedom of each atom decreases, condensing the structure as well.

[ShervinGetOffMee]

ohhhhhhh ..

thanks alot dude:) I've always been wondering that. and also the melting point of xenon is like -100? so why cant i find a video of solid xenon?

[thespurginator]

i don't know, maybe because no one uses it for anything? why make it if it isn't useful?

[ShervinGetOffMee]

well, its generally very easy to freeze, simple liquid nitrogen should freeze it. freeze it, do some weight tests? would deffinetly make an interesting video

[DrLaksative]

You could just use your head, nerds cannot lift 2,5 balloon eq. of Fe o.O

[ShervinGetOffMee]

hahaahahgaha lmfao

[andy16666]

No. Each atom of xenon is 2.5 times the mass of each atom of iron. The iron is a solid, the xenon is a gas, so the xenon is not 2.5x the density.

[ShervinGetOffMee]

@andy16666 kk but if you froze xenon into a solid... (which isent hard to do), then would it be 2.5x the density of iron?

[andy16666]

You really need *me* to tell you that?

Of course the answer is yes.

[KyuubiNaruto1337XD]

only when their masses are the same

[UncleKennybobs]

@ShervinGetOffMee Yes.

[artilistic]

my car has xenon headlamps

[hardfi123]

'Ahem, American chemists'

WIN

[sammyboy1234]

he didnt breathe it in :(

[cplai]

The drop of balloons demo is flawed. The balloon sank at different rate because their sizes are different which in turn resulted in different air friction. I remember hearing a famous experiment where Galilio dropped objects of different weight from the leaning town of Pisa to prove that the rate of falling is not depending on the mass but the cross section. Of course, the density of the gas change the buoyancy. But anyway, the two sizes of the balloons introduced an unnecessary variable.

[sammyboy1234]

big whoop

[Cream147player]

I don't think there's really a need to be so analytical over such a basic experiment with such an obvious result.

[nsaisamrit]

@Cream147player

[1997xander]

@Cream147player

Basic as it may be, it completely transformed the world of chemistry.

[pug6666]

@Cream147player Chemists thought that noble gases were inert and would react with nothing well that is not true those useless compounds won't ever form in nature they are also unstable compounds. I don't get the big deal either

[kenan6346]

surely the air resistance would be negligible in this case?

[NGC1235]

kenan6346:

No.

The larger surface area of the air-filled balloon would cause it to have to push more atmospheric gases out of its way as gravity tugged on it, slowing it down more than the balloon filled with xenon.

On top of that, the atmosphere would buoy up the lighter ballon more than it would the heavy one, causing the larger one to sink more slowly.

If the experiment was performed in a vacuum, however, both balloons would fall at the same rate.

[mmaannoollooo]

k alguien le compre un peine a ese hombre

[iplop]

I just looked it up online. (I really wish I could post links on youtube) = /

Anyways, type "Military: New Aluminum Windows Stop .50-Caliber Bullet" on google for the story on the lens.

As far as the transparent aluminum metal, type "'Hello Computer' -Scientist Create Transparent Aluminum' on google.

[FLEETCOMfreq]

aluminium oxide. its aluminium joined chemically with oxygen, creating a transparent material. not aluminium

[cplai]

Are you referring to the Star Trek movie when they put two whales in a transparent aluminium tank? But the video says aluminium oxide, not the metal.

[iplop]

Please at least google "Military: New Aluminum Windows Stop .50-Caliber Bullet" before commenting.

I am completely aware that it is not transparent aluminum.

[PattyMMelt]

At 1:17 he says there's 40 pounds worth, and I was like "Well why does it look so light?!? He seems to be holding it with no problem!" But then, hurr, I knew he was talking about money

How many dollars is 40 pounds?

[Turok2evil]

ohh crap , lol

i didn't even think he was talking about currency

i thought this was an american video , lol

but uhmm

in that case it would be about

$64 -$65

that shit is expensive x]

[grimmkillah]

75 dollars=40 pounds

[wrnchhead76]

LOL! That's really funny.

[CysicSystems]

cool story bro

[BlackRaptor31]

Radon is a more reactive noble gas :P

[TheCaptainLulz]

it probably is, but it lasts about 3 days so there isnt much to do chemestry with

[Desmaad]

In hindsight, creating Xenon Hexafluoroplatinate was like hitting a barn. Combine Xenon, the most reactive of the noble gases, and combine with a compount that contains the most volatile element in existence, and an effective catalyst, and voilà!

[tjksvids]

i live near the univesity of nottingham cuz i live in nottz. !!!!GO NOTTZ!!!!

this dude's hair is bitchin!

[Bloodsaberxy]

@aquarianbabe damn right, i'd love to see him headbang with that hair XD

[seustaceRotterdam]

I think even daring to carry out this reaction was something. It should remind us scientists to always keep an open mind never use theory as an excuse not to carry out experiments.

Probably 99% of us if we were around at the time probably would have said he was mad for trying it!

[slateflash]

Down the PERIOD?!

[scottycatman]

jeese have a seizure over a small mistake.

Yes, it's very distracting, on every damn video.

[Oz6102]

Yes cool

[iSmokeLikeItsLegal]

that hair is just out there

[supportedhousinggrad]

I think he is capitalising on [nice] Mad Professor thing. :)

love the channel as a Chemistry ignoramus.

[Draxis32]

Yeah Neil Bartlett perfomed one of the greatest chemical reactions ever, made a so called inert gases, wich could never be reacted, to react and turns out on a solid, quite and explosive solid, but god damn he did it.

[RegicidalMayhem]

Bilbo Baggins?

[NilsetJohn]

perhaps...

[veryfyme]

i couldn't concentrate on what he was saying because his hair was so friggin awesome XD

[juggliac]

I don't understand why the xenon reacts though... thank you for taking your time though.

[123IOWNALL321]

Well elements react with other elements based on how many electrons are on their final orbital. Each atom of any element has different "tiers" or "shells" in which electrons orbit around (shells, orbitals, and energy levels are all interchangeable words for this). Electrons in the final orbital are used for reacting and are called Valence Electrons. When they're exchanged or combined with another atom, they form Covalent or Ionic bonds, depending on how the electron transferred.

[123IOWNALL321]

So when you've got an atom like Xenon whose final shell has been completely filled (in which case it would not need to share, give up, or accept electrons, since it's fully stable with the final orbital completely filled), it's supposed to not be able to react due to it being completely stable. It doesn't need to share or accept electrons since its last orbital can't hold them or give them up. They evidently found a way to strip a valence electron from Xenon to make it react. Does that help?

[juggliac]

not really, you kinda just summarized what the video said. I want to know how.

[123IOWNALL321]

It reacts because it creates a "slot" in the final orbital for which a valence electron can be accepted. That ability to accept, reject, or donate electrons is called Reactivity. Xenon and other noble gases have 0 reactivity due to them having no ability to accept, reject, or donate valence electrons.

What they're doing with the Platinum Hexafluoride and the magnet is they're stripping Xenon of one electron so that its outer orbital is no longer stable, so that it can react... :|

[juggliac]

so this can be done with other inert gases too?

[123IOWNALL321]

Probably, as long as you could strip off one of their valence electrons.

[ratgreen]

why would you let yourself look like that...

[omsrswt]

My condolences.

[skodamadeddie]

mad eddiei

[grimshawr]

I wonder why platinum hexafluoride is a gas.

[0Sebek0]

may be 'cause the molecule is very rigid and with a very small dipole moment, so the intermolecular forces are very weak and it's vaporization enthalpy is low, although it may be a dense compound

[ElveeKaye]

Interesting video. :o)

[BirdValiant]

Should've breathed in the xenon....

[saintaureus]

YEAH XENON RULES!

[100000000years]

heavier material would fall as fast as lighter material unless there is a difference in air resistance.

[Ratbiker]

what would fall faster:

a pound of feathers or a pound of bricks?

[a7327626]

A pound of bricks no doubt. There is massive amounts of air resistance on the feathers.

Take away the air however...

[OrezUMoM]

if u put them in 2 bags of the same size, they would fall just as fast :)

[artman40]

Definitely in vacuum where there's no air resistance.

[zetreque]

I'd love to see that experiment where it turns to a solid.

[NoahTaylor85]

For a good example of what happens, get a rubber band and shoot it across the room. Then tape a penny to the rubber band and shoot it again.

[theep16]

think of air densities and how helium floats this is just the opposite, anyway the blown balloon falls because of the added mass of the balloon skin.

[limlynn999]

Don't pop the balloon filled with Xenon...if not waste money.

[WhatdoIdoforauser]

Lol, the denser balloon falls faster as it isn't affected by air resistance so much..

[nineaclock]

Xenon is also mixed in Fluorescent tubes with Argon and Krypton to kick start the mercury Ions. They are also put in High Pressure Sodium lamps, and Xenon Short arc lamps in Imax Projectors.
