The tiny atoms that make up our world are made up of even tinier protons, neutrons and electrons. Though the number of protons determine an atom's identity, it's the electrons -- specifically, their exact location outside the nucleus -- that particularly perplex scientists. George Zaidan and Charles Morton show how to make an educated guess of where those itty-bitty freewheeling electrons might be.
Lesson by George Zaidan and Charles Morton, animation by Karrot Animation.
The particles looked so adorable.I want to study them.
Really smart of them to anthropomorphize them. Makes it easier to follow along.
anthropomorphization is always fun
Go for it

Yes, it made the video so enjoyable!!
Also we can't see where the electrons are, because by the time the photon (light) hits it and comes back and tells us where the electron was, the energy that it took to bounce off the electron, made it move to a new location.
Oh yeah.Thanks.

I will prove in a rigorous mathematical way (using the Clifford bundle formalism) that the energies and momenta of two distinct and arbitrary free Maxwell fields (of finite energies and momenta) that are superposed are additive and thus that there is no incompatibility between the principle of superposition of fields and the principle of energy-momentum conservation, contrary to some recent claims. Our proof depends on a noticeable formula for the energy-momentum densities, namely, Riesz formula ★τa = ½ Fθa, which is valid for any electromagnetic field configuration F, in particular the one satisfying the free Maxwell equation ∂ F= 0.
@@josephlau13d77 show me the math
So a part of my body had propably been in the other side of the universe.
*****
Well, considering I have billions and billions of atoms in my body, the probability increases.
Joan well they aren't actually a part of your body.They are just electrons.
body is just a concept. btw, uncertainity applies for other stuff too. btw2, without electron, your body would stop being your body, so they are kinda essential to this concept we call out body, i guess...
No wrong, even with all of your atoms in your body, it is extremely unlikely. It will most likely never happen to any humans ever.
Valdemar Hoejlund
But it makes me wonder how far the farthest straying electron of any human or cat body will have strayed over the course of all time
Also cats because I like cats and they make me wonder things
I love these videos, short, concise and animated. Thanks for making so much knowledge available to everyone!
When you zoom into the heart at the very end, the element shown is gold. Heart of gold saying confirmed
This is one of the better explanations I have seen on this topic. Well done
Gentle and pleasant graphics and explanations!
This is one of the most beautifully explained TED-Ed videos I've seen. Good job!!
what is youtube looklike ten years ago?
It looks pretty shiny and glossy @@ahitler5592
why i learned more from youtube than one week in school ?
cuz it's less boring
cuz it doesnt seem to b just some formulas
Because your classmates were being so loud.
I have seen this cmt evrywhere.
Because you don't listen to your teacher , duh
Nicely summarized, and neat illustrations too.
What an incredible creation by such a creative and careful Designer! Chemistry is truly fascinating! Thank you for this video. It will be a very useful tool for explaining electron orbitals. I had a difficult time learning it in school, but when I understood how it works, I was amazed! I will definitely tell others about this video for science help!
I am in the library of my medical school and i can’t find the words to express my feelings right now , the clarity the simplicity and of course the fun cute animation . Huge thanks to everyone
( the zianians arwaho nahsbkom 😂)
the music ... gosh, this is amazing!!
Videos like these are why I Find it easier to understand and watch by removing the video from my screen.
分かりやすく、とても癒される動画だ
3:47 video explains a semester of high school chemistry. This is the what happens when the teacher understands the subject.
This is actually one of the most educational video of Ted
this is great video and animation work. Thumps up
So this video just summed up an entire week of chemistry!
Thanks for the awesome video!
Unbelievably well made! Please, keep it up!
2:54 That electron is so funny. :D
Perfect timingfor our lesson!
Thank you for such a sweet yet informative video! :)
Love the animations!
It's easy to understand. Big thanks😇🙏
Amazing animation!
Bravo. Excellent video. Very interesting.
Really a clear talk about electrons..!
Thank you! Great stuff!
i enjoyed the heart of gold at the end :)
The animations were fantastic.
I had 1 year of theoretical physics and never fully understand the origin of orbitals (just took them as something you must remember), and this 3 minute video just made it more clearer and actually gave a propose to the existence of orbitals in the current atomic model.
one of the best animations so far..i watch and wonder "why didn't they teach it like this in school"
Thanks ted-ed I knew I knew I could trust you about this topic.
I just love the way the particles smile. I can ALMOST forgive the elecron for being in so many moods. Superpositioned bastard!
Great video !
good timing for this video
Nice video, as always!
the isometric feel to this video was very appreciated
That buck on the mountain was so majestic
another fantastic video thank you!
Thanks it is really improve my knowledge about atoms
Kudos Karrot Animation.
2020 here, still nice video.
cutest educational vid I've seen haha, Love it!
Damn good subject video man!!. And always very interesting to learn about electrons and their very unique and strange properties and how they are changing materials sciences!!.
if there is a certain probability than an electron will be in a certain space at one point in time, does that not mean that it is in a definite space, or does it mean that they r in two places at the same time ergo superposition
if this very very very improbable event occurs, the electrons be at the other side of universe, would it be instantaneous to get there and get back, like teleporting, or would it take the photon traveling time to it?
What if dark matter would 'eat' the electrons and because of dark energy, the electrons will be shot back into the known universe
Sorry it's impossible to disassemble every atom in your body and resembled them
Well, this explanation of electrons is incomplete. An electron isn't actually anywhere in particular. Therefore it never moves. And also, electrons are not uniquely identifiable, that is to say, every electron is in principle identical. In a very real sense, to speak of one atom's electrons belonging to that atom is misleading, because there isn't really an electron there, just a probability cloud, that will spontaneously form into an electron, through a process we don't know about, should something interfere with the cloud.
So, if something interfered with this cloud in the other end of the universe, yes, an electron would form there, out of energy of whatever it interacted with. But even if this electron had its energy extracted and formed back into this probability cloud, ths electron has seized to be. Whatever new electron forms from this new cloud, is not the same electron, because again, all electrons are identical, you cannot label individual electrons like you would people.
I will prove in a rigorous mathematical way (using the Clifford bundle formalism) that the energies and momenta of two distinct and arbitrary free Maxwell fields (of finite energies and momenta) that are superposed are additive and thus that there is no incompatibility between the principle of superposition of fields and the principle of energy-momentum conservation, contrary to some recent claims. Our proof depends on a noticeable formula for the energy-momentum densities, namely, Riesz formula ★τa = ½ Fθa, which is valid for any electromagnetic field configuration F, in particular the one satisfying the free Maxwell equation ∂ F= 0.
@@josephlau13d77 Where's the proof?
briliant! simply briliant!!!
The animator did a great job, those smiley particles are awesome!!!
Thanks we are just doing electrons in science and I didn't under stand the electrons so much this helped me allot and know I know what electrons is thank you
Every high-school student needs this
the probability that a girl i'm fond of will ever like me is the same as of an electron being on the other side of the universe, not zero clearly but you got my point.
"relatable"
It's also possible that the girl who is fond of you is at the other side of the universe :)
This explained orbitals so simply. I took university chem but they never taught orbitals as easily as this!
They never explained orbitals when I did chemistry at school. That's how long it's been. But since then, the best explanation I've seen for the shapes they take is simple geometry. Try blowing up some balloons and tying them together in pairs, fours, etc. You'll see that the best possible shapes formed resemble those orbitals.
We're learning this in chemistry right now :D
i learn more from this and crash course on youtube than six weeks of school................
Aren't these two channels basically internet schools?
@@sarim9531 *_Today's school's definition is: the system railroading students into giving up creativity, logic and creativity. Ergo, these channels inevitably ain't schools!_*
Vladimir josh I agree!
Nice video.
is it may that introduce what program you have used for this clip
Good job
For some reason at 3:00 I just paused the video and smiled, so content I was with such news. I guess it just shatters our mind doesn't it?! Coolest thing ever, I think: Atoms are actually the size of the universe itself, and yet mostly very tiny - how cool is that?!
They looks so happy :D
The animation is fucking incredible. Awesome work.
This video is so adorable!
Excellent
The orbitals shown at 2:10 are given by solutions to schrodinger's equation that describes the quantum states of the atom and other quantum systems. Much like how if you project a standing wave on a plate with sand on it, the sand will fall into the troughs of the wave in a predictable way; the electrons about an atom do the same. Given the physical characteristics of the plate, only certain standing waves can be supported - based on its resonant modes. This is the same concept with orbitals.
Nice. BTW, o like the sp2 orbital ;)
Brilliant, thx!
it was really helpful
Beautiful
2:45 Is there any proof of an electron moving outside it's atom for a noticable distance? (Like 1m, then back)
Consider static electricity - the electrons are not with with their atoms.
This is very much observable fact (observable in experiments), all the quantum particles do it all the time. Quantum tunneling is a real effect, in which a particle just teleports from one place to another without any reason.
Also without this effect, we would not be experiencing the sunlight. For the Sun to produce energy nuclear fusion needs to happen, and the temperature and pressure conditions of the core of Sun are not enough for that to happen. So that phenomenon deeply rely on the fact that Sun has a lot of particles to start with, and probabilistically and statistically a few of them just randomly tunnel into each other and have a fusion reaction (very crude picturization, but basically yeah)! So overall it has some fusion going on inside it due to which we receive the sunlight.
In very basic layman terms, the superposition principle is considered both in classical mechanics and in the quantum logic approach to quantum mechanics. It is shown, roughly speaking, that in classical mechanics the only type of superposition of states is a mixture and that no pure state is a nontrivial superposition of other pure states. In quantum mechanics it is shown that, if a superposition principle holds, then the quantum logic is a complete atomic lattice.
cool animation
love this video
You should do a video on quantum entanglement.
What's the song playing in the background?
Please I need it for a school project
Excellent 😊
I've criticized some recent TedEd videos for being confusing & weak science explanations.. despite excellent Artwork.
However, credit where it'd due, this video is very good IMO.. close to a 10 for clear explaination/illustration of concepts.. including pointers to limits of what we know.
I have been explaining atoms to my little cousin recently & will show him this video later in the week, he'll undoubtedly enjoy understanding atoms more, as I will having this excellent resource to share.
"what we feel is determined on the atomic level"
thats a intresting quote..
Interesting but too short for me.
I'm going to have to do some reading...I am aware of the dual particle nature, one which is being a wave...but I've recently read of the electron's capability of being in two places at the same point in time. That intrigues me beyond belief!
Cool video, thanks for sharing!
ty!
2:38 That explanation gave me a question: is it really important that the probability of finding electrons never gets to 0?
2:46 can someone clarify what he meant about a single electron can be found at other end of the known universe?
i know electrons can be passed around, but a single electron can travel on its own from let's say (for the sake of an example) an electron of an oxygen atom to no where particular? if anyone knows an videos i can watch about this, please let me know
Perfect!
Props to the animators for all those particle faces :D
At 3:29 that is a heart of gold
It's to do with with The Pauli Exclusion Principle. There's a Brian Cox lecture on it, I think it's called 'a night with the stars'. I find videos explain it best
hahaaha heart of gold
cmor835 cute
the title seems to be flawed. it reads, "The uncertain location of electrons" but not only electrons are like that also protons,quarks, and I think all the particles.
The model says that an electron will be located at random places and that we can never be certain where it actually is at a given time. We can only say what's the probability of it being in some part of space. That probability decreases with distance from the nucleus, but it is never zero, no matter how far you go. So there's always an extremely, extremely small chance that the electron is actually miles away or even on the other side of the universe.
It's sorta like the foam in the ocean, if you agitate the water enough you get foam; when enough energy is put into a small place you find a boson of the type described by Peter Higgs. If you just move your hands fast in the air, you get no foam, but if you do it on the ocean you do; similarly if you crash two particles fast enough and you get the Higgs boson, it shows that you are indeed inside a Higgs field. But it is hard to find it, cause like the foam in the ocean, it disappears with time.
anyone know about david lapoints primer fields? i would like to know how scientifically sound is the theory?
A very astute observation by you.
The answer is the Weak Nuclear force.
Also, the nuclei of all atoms have neutrons except Hydrogen.
A reminder of why I love chemistry and picked it for the HSC
i just learned about this in chem today
the differences in the electron orbital can easily define an element as magnetic, or even plasma. if there is but one orbital centered around the nuclei the electrons are traveling in an elliptical pattern around the nuclei, constantly changing the angle at which they orbit it.
if there are two orbitals, the electrons are likely traveling in a single beltway, elliptically in a toroidal format making the atom a magnet with two poles
the uncertainty factor is because....
This was pleasant.
Lol the nucleus of that neutron keeping site with that fast moving electron!
Correct me if I'm wrong anyone, but electrons have kinetic energy, which is part of what moves them away from the nucleus. But the positive magnetic force of the proton holds it close. For an electron to just become stuck to the nucleus would require it to lose all its energy, I guess, which I'm pretty sure would make it not an electron. And besides, it would be pretty weird to explain bonding as well with just an electric field.
I wish they have shown what an electron cloud looks like. Like that electron was moving really fast in it's orbital.
The author of this video meant that by our power of not being able to observe the location of the electron, it can pop out and back in into the existence.
But in reality, the electron isn't moving anywhere except around the nucleus in a wave pattern, or, when there is a reaction with different atoms.
more correct and understandable that my high school lessons
