  • Awesome tie.

  • Okay... So less simplified it means that the muon is hanging out so close to the nucleus of the helium that it leaves room for another electron to fit at the outermost level... The odd thing is that the entire molecule will have negative charge even though it isn't an ion... Wow.. What the hell?

  • @anxez No. Not quite. Helium has 2 electrons. 1 gets replaced by a muon. Leaving 1 normal electron (in a normal electron orbit) and 1 muon which has a very low orbit. There a 2 pos charges in the nucleus and 2 negatives - leaving the whole thing neutral.

    This leaves only 1 electron available for chemical reaction - so the chemical reactions take place rather like hydrogen (the muon is ignored because its orbit is too low).

  • The "Poliakoff Vegetables Allegory" is going to be a huge hit all over the places!!!

  • Interesting! I wonder how they analytically measured this new 4.1 helium.

  • I'm a chemist student still early on my university studyes, but i found the naming a bit odd.

    The new atom (4.1H) still has a helium nucleus (2proton + 2neutron) so shoudn't it still be named as a helium atom with something indicating it's changed electron status? 4.1H is going to be misleading, because first reaction is, that it's a hydrogen atom with odd mass, and not as a helium atom with odd electron placement.

    I think it should keep the Muonic Helium and keep it's (He) as the base symbol.

  • The implications are endless!

  • When you stir up your mind, it's like soup and all kinds of vegetables will float to the surface. Vegetables like cauliflower. =D

  • @Phoboskomboa I have alphabet soup stirred up in my mind and the result was "DERP" lol

  • he uses any sphirecal shape to represent atoms :P

  • This is still blowing my mind..

  • epic science has epic tie

  • what's the practical advantage of this, or is it just the principle?

  • @Henry1993bc this means that theres a possibility of making molecules with not yet known properties, maybe stable ones.

  • @VarykGerai ok cool, thanks

  • @VarykGerai The muon decays in about 2.2 microseconds.

  • @materiasacra Isn't it in 2.2 picoseconds?

  • @materiasacra nvm you were right, I checked on wikipedia =P

  • he has epic science hair

  • It's high to time to get the Prof some proper atom models.

  • So in fact they made of two electron shells, an inner one with the myon and an outer one with the electron, so they had Helium that can react because it valence shell had only one electron, did I understand this correctly?

  • @CoxTH Sorry for writing muon incorreectly, I'm German :D

  • @CoxTH i think so

  • @CoxTH yes

  • Ditirum is cool shit. If you consume small amounts of ditirum oxide it actually reduces the effects of aging.

  • thats a cool tie

  • This is amazing

  • I don't see the avail of this recognition.

  • HAX

  • you have some tasty hydrogen atoms there :0

  • i love his tie

  • @Hazardouscheese Awesome

  • Comment removed

  • Anyone else thought he was gonna say i shat bricks after 0:09

  • Why would they call it Hydrogen 4.1 instead of Helium 4.1 if it has two protons?

  • @Canadarocksish I guess they call it this way, because chemically it reacts more like Hydrogen than Helium (I don't know if He reacts at all, maybe with F, maybe not). And I also guess it is 4.1, because the mass of a muon is about 1 tenth of a proton, thus the mass of the atom is 4 + 0.1 = 4.1

    It's a guess though, I can be terribly wrong.

  • @upisoft2 I think it should still be called a helium, since the amount of protons in the nucleus is unchanged. proton count is the only relevant part of atom to determen what is the name of the atom, since you can change electrons to make an ion, and you can change neutrons to make an isotope.

    Only changing the protons should ever change the name of the element, and that thing still has the protons of a helium.

  • @Somezable Actually chemistry is a science that is not interested in atom's nucleus, but rather the electron shell around it. That shell defines the chemical properties of the elements. Actually without particle physics that discovered the nucleus of the atom chemistry was still viable science by itself.

  • ho else wants to know more about muonic particles

    thumbs up if you do !

  • did the professor trim his hair? :(

  • I like the professor using "Cuties" to illistrate his point across, To me a Layman.

  • "Your mind is a bit like soup. It has to be stirred up all the time. And then interesting vegetables float to the surface, and so on... and you have new ideas."

    Wonderful. I'm simply going to *have* to try this out as my new pickup line at my next party.

  • Was this molecule stable?

  • @madjimms did you even watch the whole of this video?

  • @MrBigape1 Yes...

  • @madjimms I would venture to guess not. Pretty much all stable configurations are seen in the wild. And apparently no one has ever seen this form of He before. I suspect it was all over in the accelerator in less than the blink of an eye. I wonder if we'll be seeing more "muon-ated" elements in the future.

    Not sure what MrBigape1 is complaining about. The information is not there.

  • @sbergman27 Thank you for a respectful & informative comment.

  • he is like the scientist from fringe lol

  • that's my favourite periodicvideos video so far

  • That tie is beyond awesome!

  • This channel makes me so happy. Really my favorite on YouTube. yay!

  • That is the best ( and funniest) metaphor for a mind I've ever heard.

  • Comment removed

  • So would muonic hydrogen make a good reactant for fusion? Or you need such high temperatures the neg charges are immaterial? Just a thought...

  • This man is incredible, he drinks his coffee out of the periodic table.

  • Excellent Thanks!

  • The mass number of muonic He is 4.1 because a muon has 0.1 x the mass of a nucleon (neutron or proton), and, thus, would essentially act as a 0.1 nucleon: mass number = 2 proton + 2 neutron + 0.1 muon nucleon = 4.1 ...

    Not so strange, really !

  • Comment removed

  • Muonic He, apparently, behaves just like an H isotope (3 neutrons). It's added muon is 200 x heavier than an electron, causing it to travel so close to the nucleus, it becomes part of the nucleus, effectively uniting with a proton to form a virtual neutron. To the remaining outer electron, the nucleus "feels" like it has one proton and three neutrons (two actual neutrons and a virtual neutron consisting of a muon + proton). Thus, muonic He with 1 outer electron chemically behaves like H.

  • @DrakeMan4

    Thanks for this explanantion!

  • The reaction you describe truly is amazing! I never would have imagined such a thing. Muonic Helium, simply amazing. Does the muon orbit at a lower level than the first electron did? Well it seems that it does. That is too funny, the nucleus can be tricked into thinking its first electron orbit is full, when it really is not, hahah.

  • can someone answer why it is helpful to have hydrogen 4.1

  • @1KevinsFamousChili1 Shut up you moron

  • @UncleKennybobs wtf? That was a legit question! How about you stop trolling 13 year olds who are way smarter than you and go do something useful, like be a matinience guy at the zoo, or even better, how about you go prove the the first law of thermodynamics wrong and completley disappear off the face of the earth!

  • @1KevinsFamousChili1

    People never tought it was possible.

  • His cup... That's EPIC !! :D

  • Brilliant stuff! Keep the videos coming :)

  • Comment removed

  • I love how many hidden periodic tables there are in this!

  • everyone can realize how confusing is that text if you just think that even profesor poliakoff didn't understand it at first reading!!!

  • Loving the soup analogy!

  • Not being a chemistry buff, I have to ask: If helium has two electrons and it's the electrons of a pair of atoms that bond together, why can't one of helium's electrons bond and the other continue unbonded? I don't currently know what would prevent this.

  • @Tbird761 nature want to have a highest chaos and largest stable status in bounds . if you have a low amount of energies you are stable. so it is energy inefficient to bound . and it doesn't doesn't help enough whit chaos so it is not interesting for the atoms to do the bounding. (that at least what i have learned in chemist lesson )

  • great mind\soup parallel !

  • Correct me if I'm wrong, but does the muon occupy the same shell as the electron? I would guess not because then, Pauli's exclusion principle wouldn't let it bond with hydrogen. Then does that mean they have discovered a lower energy shell than 1s where the muon resides?

  • @fabricofspacetime fantastic question, I await for an answer as well

  • @fabricofspacetime

    The Pauli exclusion principle only applies to identical fermions. Electrons and muons are both fermions, but are not identical.

  • HUH? WTH i do not understand

  • I ate all my vegetables in my soup. the Particle gods will create water 8.1 that's what I'm waiting for, I'll make my soup with it.

  • 3:27 LOVE IT, LOVE IT, LOVE IT !!!!!

  • nice prescription safety glassses!

  • This is a very humble man. Not only intelligent, but also wise enough as to publicly recognise he never believed something actually could happen and even praise other scientists works.

  • @DerAnstifter well of course; he's a professor, it's his job to teach of other peoples' work. If he was a research chemist it would probably be slightly different

  • @DerAnstifter It's called being a skeptic. Something everyone can benefit from...

  • Comment removed

  • So would this chemically be the same as Hydrogen or as Helium?

  • @HazMatLabz neither

  • aww, those sneaky, sneaky MUONS! They're EVERYWHERE and I suspect that they're breeding...

    THANKS, PeriodicVideos for these interesting posts!

  • 0:37 reminds me of one of my old girlfriends

  • Thanks for stirring my soup!! ASK NEXT TIME

  • I wonder if there's anyway for chem students to get a summer internship working with the Periodic Table of Videos team.

  • finally, something i understand

  • perfect!!

    

  • Anyone had a recipe for brainsoup?

  • Where does the professor get his papers from? Is he subscribed to a science journal?

  • "interesting vegetables" lol

  • Brilliant soup analogy, a mind is a terrible thing to waste. I read with interest an article saying there is a hidden genius in everyone, you just have to work hard at it.

  • What would be the application of such a discovery?

  • I LOOOVVVEEEE ORANGES!!!!!!

    ORANGES FOR PRESIDENT

    SEND ORANGES TO THE MIDDLE EAST TO SORT THAT SHIT OUT

    OSAMA IS DISGUISED IN ORANGES

    ORANGES = No 1

    ORANGES SIMPLE AS!!!!

  • great video... i like to eat oranges ..good job

  • annoying orange ftw

  • Really cool, thank you

  • watch?v=IKRmKqp2FwY

    watch?v=IKRmKqp2FwY

    watch?v=IKRmKqp2FwY

  • Bella Cravatta!!!

  • SNOOOOOOOOOOOOOOOOOORE

  • The physics of particles interacting at the atomic and subatomic level are so fascinating -- especially when you realize that they're going on a quadrillion times over just in the room you're in now, every moment... and that what we think of as macroscopic physics is due to the aggregate result of trillions of atoms interacting. Physics at the levels we can see sometimes seem more like crowd behavior or anthropology than pure Newtonianism!

    Thanks as always for your brilliant videos!

  • EPIC! I want to read this paper too!

    ^_^ I'm also loving that tie. :D

  • whut duuuh hell ?

  • does it count that i eat vegtable soup everyday? anyway thank you for the video great brain food :)

  • That is a neat trick! Due to relativistic effects, wouldn't the muon last a bit longer?

  • The bit about "stirring" the mind like soup really describes why I watch these videos in the first place. xP

  • I'd never heard of a Muon, amazing, and I'm sure there's going to be more where that came from in the future.

  • BUT WHAT DOES IT ALL MEAN?

  • "Again and again for scientists if they hear something surprising that makes them think in a different way, it's really good.

    Your mind is a bit like soup, it has to be stirred up all the time.Then interesting vegetables float to the surface and so on.....and you have new ideas. If you just sit there, it all stagnates and it gets boring."

  • somebody's got a good shot at a nobel

  • epic tie

  • That attitude of staying curious, even if it might not have any practical use, we owe:

    • microwave ovens

    • penicilin

    • computers

    • surgery

    and a lot of other utterly useless stuff…

  • This is brilliant!

    In our physics, we learned about muons last semester when we learned about relativity, but I wouldn't have expected this to be a viable use for these particles.

    One question though, if you use a muon for this purpose, what happens to the muon when it disappears (the muon half life is very short), would you some how get a He^+1?

  • this is shit

  • @AMYYD0LL No, this is THE shit =P

  • His tie... that's EPIC !! :D

  • @alfonskilla but never too epic

  • @alfonskilla in another video he has an alkalai metals tie :D

  • Thank you.

  • This blows my mind! I wonder if any stable molecules could be produced by substituting electrons for heavier heavier leptons like this...

  • Could is be possible to synthesize Helium by forcing H2 to share the same space?

    Additionally, would it be possible to force an extra proton into a Hydrogen atom and bond it to a Helium to get the extra electron to meld in.

  • I like your tie. Very fashionable. Where did you get it?

  • Co ja ku**a  ogladam ?!?

  • The name is bond, Heliun-hydrogen bond!!!

  • Listen Mr. "Noble Gas", You're Going To Mix And Bond With The Common Gases And You'll Like It!

  • What the hell is he talking about?

  • Comment removed

  • he's obviously talking about fruits and oranges... can’t you tell??

  • @parmdeepbinning i dont know...MAYBE ATOMS?? MORE SPECIFICALLY HYDROGEN AND HELIUM???

  • I also enjoy interesting vegetables :)

  • I'm not gonna pretend to understand exactly what he's talking about because its been so many years since i've studied chemistry (back at gcse)....10 seconds into the video all I could think about was eating those mandarines...

    ..also Prof looks like cool with that funky hair style..

  • Good stuff, Interesting Video!

  • Did they actually use oranges in the experiment?

  • Think I'll wait for Hydrogen 4.11 Service Pack 2, should be more stable :-)

  • @dajwilkinson probably gets better reception too. 

  • @dajwilkinson But is there an app for my iPhone? There must be because there's always "an app for that."

  • @dajwilkinson funny !!!!!!!!

  • so simple just magnetism and centrifugal force vortex them and you should get even better mixes of atoms

  • noooooooooooooooooooooo, i liked his hair! i wanted that hair!

  • @mrKaLLeKLovN Did U check his tie?

  • @walkandlookup what about it? it's just the periodic table! his hair was awsome!

  • are you going to fill those oranges with helium or not?

  • wtf should i do?

  • Brady thanks for placing the sixtysimbols video where they talk about the muon.

  • i knew shis could happen theres till more and more things we can do with atoms and all the masses , since ohoton have mass we can play with them to

  • can you imagine the applications of these if they were stable?

  • I would like to read more about this. Is there a link to this article? I would like to know how long the Helium Muon combination remained stable.

  • wow! my mind is blown

  • Prof. Have you had a haircut?

  • cool i always folow your vidoes this one was pretty cool cuz its little strange and if he wouldnt explanied it to us i would have to google it and if did i wouldnt undrestand any thing cuz they talk too detald and im still in grade 10 :)

  • This is very interesting, hearing how and why these experiments are done. Thanks.

  • HeH, amusing . . .

  • stupendous

    

  • I used to get high on Helium when I was little.

  • Nice haircut.

  • @TheTereminator he said Muon....

  • I think my mind just had a meltdown... does that mean it's soup now?

  • That's very interesting! Going around the Pauli exclusion principle by replacing one of the electrons in Helium by a muon, very clever indeed.

  • @ConsciousAtoms I believe it's more like having the electron to the 1s and the muon's mass make it so slow and closer to the nucleus compared to the electron that the muon is somehow like in 1/2S level, so the electron is now like a valence one

  • @OursHommePorc I didn't read the article, so maybe I am wrong. But my understanding of quantum mechanics tells me that both the muon and the electron should be in the ground state, because nothing is preventing both from being there. The reason normal helium does not form bonds is the Pauli exclusion principle: helium can only have 2 electrons in their ground state around it (one spin up, the other spin down). Muon helium does not prevent such a bond. (cont'd)

  • @ConsciousAtoms (cont'd) Another way of looking at it, it seems to me, is by considering the helium nucleus plus muon as a single particle (consisting of 2 protons, 2 neutrons and the muon), with a single electron orbiting around it. In this view the particle can be considered - as the professor explains - as a super heavy (and very unstable, by the way) hydrogen atom.
