Xenon in the Sand - Periodic Table of Videos
HTML-код
- Опубликовано: 13 июн 2011
- The Professor discusses a recently published theory about Earth's missing Xenon.
He happens to be on Rio's Copacabana Beach - but that's just because we were there on other business.

Laminated periodic table, made specifically for use at the beach.
The title made me think this was a music video for a second... I could just imagine the professor singing!
he should be in a swimsuit calendar
I can see the Professor always likes an idea that makes people think, and I can't agree more!
I learned more from watching your videos than i did from my high school chemistry class.
Silica is known to cause a lung disease called silicosis. Ive always wondered, are there any particles of silica small enough to cause lung damage present on a beach? Obviously people arent dropping dead after visiting the beach, but I still think it would be interesting to know.
I am not usually one to comment on such trivialities as the good professor's appearance, but I must say, the salty, humid Rio air is making Dr. Poliakoff's coiffure particularly fierce! Brazilian Blowout indeed!
Perhaps something on the nature of hygroscopically induced stranded keratin helicity enhancement next?
2:04 watch out professor
Great video to end my day.
2am in the morning and just finished physics assignment.. Chemistry next.
I'm terrible at it, but I think it's interesting.
I live these videos, as usual :)
I remember my chemistry teacher teaching me about Tetraxenongold, which is a compound made from two famously unreactive elements. Can the professor can shed any light on that?
How did the xenon get specifically into so much sand?
And would there be other elements trapped?
Closest I'll get to Einstein at the beach.
this fine man has the coolest white man afro ever, just watch it flow in the breeze~
Although I'm electrical engineer, I can truly say that professors attitude to chemistry made we want to 'cheat' on my masters. In other words I have gotten infected with chemistry and so did my wife and children why by the way are only 4 and 5 years old. And maybe if I'm lucky enough I can meet professor as well you guys and ask all of those strange questions regarding chemistry. Best of luck! And keep infecting people with knowledge and passion, which is far far away from mind deceasing TV.
starked1 I think that identifying this using mass spec would hardly be possible. As the Professor said, the amount of Xe is probably well under the ppb or ppt concentration, hence it is well under the limit of detection of any mass spectrometer available as today (2015).
Love these videos!! And his hair !!!
Just a thought about the Xenon in silica. With today's mass spectrometers being so sensitive might it not be easy (relatively) to melt a large quantity of sand (you would know the number of atoms). With the differences in B.P. and M.P. of the two compounds it should be relatively easy to analyze the resulting vapour given off and see if it contains any XeO4 (sorry for no subscript)? Maybe this is a dumb question. Thanks again for the videos - my students love them. Cheers
you learn something new everyday, thanks!
I love how many periodicvideos videos we are getting!
*thinking about the excellent camera work, and all of a sudden*
"Tell me what you think of my wife's camera work as well"
Woah.
I love these videos!
I love how the professor wears interesting ties. My H Chemistry teacher wears interesting ties as well..........coincidence? I think not!
Professor come back to brazil more times we love you and your periodic videos crew!
great video
The cherry trapped in the cake. I will remember that. :D Excellent 'stage set' for a teaching video! It made the lesson fascinating, really! Sell the DVD to educational institutions for their classes.
@Starter61 Yes, you could say that. Xenon is interesting because it is explaining the answer to another question that exists. "Where is all the Xenon that is supposed to be in the atmosphere that the theoretical equations predicts?"
Xenon being in sand explains that anomaly.
The Prof. managed to avoid the waves but what about the cameraman? At the end there,it looks like he must be in the water :)
Please visit the RWTH University of Aachen in Germany. I am a big fan and I would like to see you. Our Professor showed us a video from your channel last week and all the students loved it. :)
0:11 "paint me like one of your french ladies"
Prof. Poliakoff has been goin on a lot of field work since recently GOOD FOR HIM!!!
Gotta love the professor :D
@periodicvideos That has got to be the only tie around for miles.
Will there be a future video about super sand to purify water? Though I guess it is really simple stuff, that's what makes it so potentially usefull.
It's nice to know I've already encountered Xenon without knowing it. It's a nice surprise.
I think it would be great if you discuss papers and you link them in the description
They could call it Science on the Beach.
Come to Campinas, please...
I would totally buy a 'PeriodicVideos' callendar of the professor in relaxed poses on beaches. For charity, of course.
Also, FREE XENON!!!
@michdudeada Hey, thanks for the quick and clear answer. Actually, I was not aware of the Xenon paradox, although, as I found out later, it is mentioned in the video.
Molecules incorporating noble elements like Xenon, while possible, are unstable. Most likely, despite the bonds, reactive elements remain unsatisfied.
It's like having a terrible girlfriend, but she's the only one available at the time. You won't leave her until you find someone more satisfying or get rid of the middlemen.
In this case, the oxygen somehow couldn't find anything else to bond with. So it bonds with whatever is available until something else comes along. That's how I see it.
I was thinking the same thing. They gotta get on that.
2:47 the pigeon went to hide in the professor's hair
I would like to see the Professor dancing some Samba!
any known trapped elements or compounds out there? any more cases like this?
i mean not the usual gasses disolved in water, but things like this-
atoms trapped inside molecules, like the way water is trapped in silica-gel.
if i saw martyn in real life i would come and say hi. :D love your videos
Whats the professor doing in Brazil?
the professor looks so creppy if you watch this on mute, but if you listent he is awesome.
When you are recording video in public places like this, how many people stand behind the camera anxiously waiting to talk to you and the professor? Thanks!
@McFluffensteinn now THAT would make me fall off my chair, like you see sometimes in cartoons and anime :P
the preview image makes me think prof poliakoff is going to do a music video :P
Twice recently I have walked past the prof in Beeston (near Nottingham Uni) where I live and it's a bit like walking past a rock star.
I had a dream once, quite similar to the introduction of this video
new video, great way to start a monring!
bloody hell, what time is that? the beach is deserted!
I like his pose on this beach... very dreamy
@periodicvideos I see a lot of different periodic table of videos on facebook. Which one is actually ya'll? I would be your friend easily :)
hmm... copacabana beach.. now I'm imaging Barry Mannilow singing the elements song.
Cherries? Cake? In my household we never saw a cherry, let alone cake.....
I would totally buy a 'PeriodicVideos' callendar of the professor on different beaches in relazed poses. For charity, of course.
Also, FREE THE XENON!!!
perfectly dressed as per usual prof! not quite appropriate for the beach, but close enough!
I wish I was on the beach, in Rio de Janeiro, in Brazil =/
Have they not attempted to look for Xe in a large volume of sand then? I would expect that if you suspect this sort of thing, the very next order of bussiness is to find out how to best detect Xe in (SiO2)n
How do nobel gasses form molecules at all, I was taught that atoms formed molecules so as to fill their outer shell. But nobel gasses have their outer shells filled already, so what happens.
please come to Campinas - SP, if you guys come to SP, please let us know, i am pretty sure that there will be A LOT of people instrested in metting all of you (= PLEEEEEASE
Is there any idea as to how the xenon ended up there in the first place?
interesting, but almost anything small enough in the right quantities could cause lung damage even as eg. fine sawdust
i totally wish you could come to our school :/ too far away (ukraine, kiev international school)
On a day like today
We pass the time away
Finding xenon compounds in the sand...
What is the professor's name?
we should analyze some sand
The Professor almost looks like a mermaid with brains... almost.
I've never seen a tie worn on a beach. :P
I would like to have seen an animated demonstration with his lecture.
~Thanks from Max in Florida, USA.
I want to be a chemist just for the travel!
You should have mention some interesting stuff like how sand is used to power your computer! (the CPU and GPU)
I was hoping to see Neil in swimmer ware...
Wishful thinking!
There's like a brazilian Xe's on every square meter of that beach.
Should have went around the bend down a bit to Ipanema and talked to the ladies, I wonder what the difference is between the two beaches that are practically side-by-side?
ill remember you Xenon for what you odid top my Xenon
im going to forget all that sht but thats amazing right now!!!!!!!!=)
This guys hair makes him smarter.
Xenon trioxide explosive? You know what you have to do....
Chemistry, chemistry EVERYWhere!
Or call it a sunny year with dr Polly
poor camera man at the end
@FortOrdDirt
or to start an great evening (6.52 p.m.) :-)
Hey Professor! Come to the south to join the chemistry of chocolate, in Gramado, the brazilian swiss city! :D:D
@periodicvideos Ye gods!
@seantfu I would be!
I thought Xenon was inert and couldn't bond with anything?
@pikachuthesquirtle Apparently people with a scientific interest in the sand do.
@wilfred8686 its possible because there were 16 XeO3 molecules trapped hidden in the thumbs up button that exploded upon release :-p
@periodicvideos No way that's true... I would be there.
lol the Professor was on the beach for the lady's.
Dear Professor, under the same logic, couldn't just any small particle be trapped inside the sand ? What is so special about Xenon ?
Xenon, girl of the 21st century
I wanna see the Prof mackin' on the beach bunnies.
Alternatively, the Xenon is like Bowser and managed to get between Mario and Peach. The two are trying to get together, but Bowser is acting as a barrier. An external force has to be applied to remove Bowser and get Mario and Peach back together.
