Arvin is incredibly unselfish with his knowledge. We all are so lucky to be able to have this opertunity. Each video Is a gift to each and every one of us. I would like to personally thank you from the bottom of my heart, sending you much love and appreciation from a loyal subscriber.
@@ArvinAsh you're one of the most genius teachers of all time Arvin Ash, although you're not perfect, and i disagree with some theories you show In some of your videos, you are one of the best when it comes to making complex things easy.
My school years have been decades ago. I wish I had teachers like him to explain these topics maybe I would have had more interest in science as a kid. Doing a lot of catching up now
I feel the same. But tbh I think it has a lot to do with when we were kids, we can be very closed minded, so if it didn't peak our interest right away we instantly turned off. But as we get older, especially in my case, we become more open to learning things and actually enjoy learning new things. It's that old saying I wish my younger self had the attitude I do now. I enjoy learning and will try even when it goes over my head.
Wow this is the BEST video on nucleosynthesis on YT. Arvin accounted for every nucleus!! The 4 heavier elements after Pu and Li, Be and B - everything!! The level of detail in this video is mindblowing. Moral of the story - sufficiently energectic protons and neutrons can do ANYTHING 😂😂
Many documentaries satisfy the “ what is happening ” but getting someone to at least attempt to answer the deepest “Why it’s happening” is great. thank you
The rarest element on Earth is Arvinium, made by fusing together large pieces of knowledge. It's radiating away wisdom, and it's detectable on youtube. My favorite element, for sure ❤

Fun Fact : Uranium nucleus's is energetically more stable than Nitrogen's nucleus But it is easier for heavier element to go under nuclear fission ( it has a smaller activation energy/energy barrier) while for lighter elements is difficult to go under nuclear fusion ( it has a very large activation energy/energy barrier).
I think you meant to say fission again. Lighter elements are the ones used for fusion. Due to their tightly bound nucleus with smaller atomic radii it is harder to separate the electrons from their opposing protons so closeby. Uranium has a very large atomic radii with the outer layers of electrons very far from the nucleus, making them much easier to remove with much less activation energy. Fission is exothermic, releasing energy from the breakdown of larger atoms. Fusion is endothermic, building potential energy by fusing atoms together. . I have a feeling you already knew all this and that this was just a simple typo. As far as your fun fact, I believe the nucleus being more energetically stable is due to strong forces right? Chemistry is so cool!
@-889 true till you reach iron, getting heavier eats more energy than it produces. Thats why elements above it come from supernovas and neutron capture
@yfaiell3263 Why do you mention electrons? You dont need to ionize an atom to make fission.(seperate electrons=ionize the atom) and its not correct that ionizing a smaller atom is harder, its sort of the opposite, but not quite. Ionising Hydrogen is pretty easy(~13eV x 1 electron=13eV). Completely ionizing (making plasma) of heavy atoms is very difficult and needs lots of energy even if it is really easy to kick of a single electron(Iron ~7eV x 26 electrons=182eV).(elements left in the periodic table have smaller ionisation energys per electron, noble gases have the highest ) (Cesium lowest, Helium highest per electron) But besides of that you are talking chemistry here but its a nuclear and not a chemical reaction.(even if afterwards chemistry will "happen" to the products) You need to make a neutron, ideally a slow one because the probability then is higher, destabilizing the Nucleus to split it via coulomb-force(like charges repel each other) overcoming the strong and weak force in certain parts of the nucleus. For fusion, the problem is the coulomb-barrier. What you are using in the fission is the problem in the fusion. Make them hit harder(heating makes them faster)or crunch them harder together(increasing the pressure) and they fuse together releasing energy and particles depending on the elements. For the fission a proton with high enough energy would work but since neutrons are neutral and dont feel the force they are the only one who realistically can do it.
The whole idea of non-natural elements is so cool! Like, a lot of times I feel like we are just little blips of order living in a universe that wasn't made for us. But the fact that we can make actual elements that actually exist that have never ever existed before (that we know of) is super cool.
@@loganwolv3393 It's neither, it just is, it's probability, throw enough darts at the dart board blindfolded and you'll eventually hit the bullseye. Billions of chemical elements and molcules (and molecules are in space) going through billions of environmental situations, on a billion planets, and you'll eventually get something once in a hundred of billions of years. We're not made for it, we essentially are it. But meaning is a subjectivity created by the brain.
we're gods. we're even on the verge of making artificial suns. scale that up with future developments in technology and we can postpone the heat death of the universe indefinitely
I am personally very much Greateful to you Arvin. Like, I'm in India and I'm a science aspirant who's in 12th standard who was searching for such a channel which would cover all the enthusiastic topics in science 🔬🚀 I'm glad I found your channel and gain knowledge📚. Really really appreciate your work sir. Thank you❤
Prajwal, this excellent video told you the current paradigm for how the elements formed. This is not the end of the story. There are probably many other pathways that could not even be imagined yet. That will be your job. Just as an aside, there is a small amount of elements formed by a natural nuclear reactor in Africa. As someone said, "Reality is not only stranger than we suppose, but stranger than we can suppose."
Great video! I taught astronomy for several years at the 2 - year level. I wish I had videos of this quality back then. They would have been so useful to help my students understand how everything came to be.
Hello. . I have been watching your videos for a while, but I wanted to thank and encourage you. You are amazing and have some of the absolute best science videos I have seen. Thank you for being you!
Heavy elements are created by: 1. R-process: Ultra-rapid neutron absorption without sufficient time for decay between neutron impacts. 2. S-process: Repeated absorption of neutrons with time between impacts for some decays to occur. 3. F-process: While energy cannot be liberated from fusion of iron and more massive elements, such fusions can and do occur. Thermodynamics favors such endothermic fusions at sufficiently high temperatures. Such fusions can cool the core of a star, accelerating collapse. Such fusions produce high mass nuclei, which quickly decay into more ordinary elements. 4. I-process: Inverse fission caused when heavy nuclei collide (as in F-process) in the presence of very high neutron fluxes during supernova explosions. This process is approximately the reverse of ordinary nuclear fission. 5. N-process: when outer layers of tentative neutronium are bounced off of cores in supernovae, and are ejected from the stars, then spall into ultra-massive nuclei that quickly decay into more stable ordinary nuclei. Not all of the above processes are distinct, but rather grade into one another. Furthermore, the initial rarity of the heavy but relatively non-reactive elements is exacerbated by the process of the formation of the Earth's core. These elements do not readily form oxides, but remain in elemental form. As such, they are soluble in the molten iron that makes up most of the Earth's core. They were therefore dissolved out of the original molten mass of metal and rock and descended to Earth's core. More reactive metals, like lead, for instance, DO readily form oxides. Hence, although lead's cosmic abundance is far lower than that of gold, it is far more common in the crust where oxides prevail.
How can we say those heavier elements don't exist in nature when nature can get crazy with pressure and heat. I mean aren't neutron stars made of then? I always have a thought maybe they just decay so fast that they might as well be man made. I really hope the island of stability comes true, and that we get some magical iron man type materials from creating it, lol. At least an Arc Reactor or some crazy propulsion material/fuel for space travel.
Thanks Arvin for another fantastic video. I really learned a lot from this video. How wonderful it would be to have as a collector's item the first Hydrogen atom created by the universe !!!
Excellent video Arvin!!! Most exhaustive account of the whole periodic table. Can u do a video on the detailed physics of pulsars, what causes their extreme magnetic fields and how they emit light beams?
Simply Arvin, your channel is pure treasure! I’m rich to know all of your videos! I really think so! Thank you very, very much! What I think, who ever come a cross your video, he become your subscriber immediately! I guarantee you, because it happened to me too couple years ago!
This is one of the best explanations I’ve ever seen. If you can suggest further reading, even technical, it would be appreciated. Thanks,! Your videos are consistently great.
What an upate. When I first heard about this topic, there were only two elements, not three, that emerged from the Big Bang. In addition to that, Arvin's video was packed with other new information and was, as usual, excellent.
Enjoyed this video Arvin. There are many videos by physicists explaining stellar nucleosynthesis, but they stop at the part where Iron is formed and do not explain how the rest of the naturally occurring elements are formed. Thanks for explaining, what is, i am sure, a complex topic, if one tries to understand it theoretically from the perspective of the limits placed by energy at the nuclear level.
This is super interesting and educational. High school science and chemistry made a interesting topic so borning, i wish combine something like this in the educational system.
It looks like weak force holds very key importance in formation of these heavy atoms. I do have one question: Why does the isolated neutrons get captured by these heavy atoms? I assume that these atoms are in stable state so there must not be any reason for them to capture these neutrons. Is there any mechanism behind this phenomenon? On the side note I really appreciate your work. The way you explains these complex topics in layman terms is astounding. I am glad I was able to witness the growth of this channel from under 50k to now 583k subs. Hopefully you'll reach the 1 million milestone quickly.
Neutrons are being absorbed and released all the time, in very large scales under the right conditions, high temperatures and pressures. A tiny portion of these exchanges result in stable elements being formed with the help of the weak force. This is why typically, higher mass elements occur in lower quantities than lower mass elements.
Thanks for yet another wonderfully clear explanation of an interesting aspect of our natural world. For me as an interested lay person, you are the best science explainer on the internet, that I have found so far anyway.
I pondered whether Life could exist without heavier, rarer elements. Looking at the periodic table I observed that with a few exceptions, notably iron, copper, calcium, and potassium, living systems we are familiar with are comprised almost entirely of low mass elements. Elements heavier than iron and copper are only incorporated in trace amounts. This implies that Life could arise quite early in the observed lifetime of the Universe. "Organic compounds" might well be able to provide the activity of all those trace elements, or those activities may not be necessary to Life.
as per the scientific theories we can see the pattern, first ions were created, as per expansion of the space those ions tends to lower their energy by surrounding the electrons (resulting an atom).. after creations of an atom, atoms further stabilized it to make molecules, and released the extra energy in universe to increase to entropy which shows the expansion of universe, but there will be some point when all the surrounding energy will be greater than individual matters and again matters will start to break and big bang occurs..
i’m studying nuclear engineering at university and i love seeing what this kind of video. what i learn in a class setting is shown in a more entertaining fashion, and is pretty on par with material. though that fancy process for heavier elements is called neutron absorption followed by beta particle decay. great video though super entertaining
Would it be possible for you to make an additional video covering the same topic, but from the point of view that the atoms are made up of particles that are vibrations in underlying quantum fields? That is, could you explain nucleosynthesis etc in terms of what is happening in the underlying quantum fields? I would also greatly appreciate some guidance to the following additional but related question: If it is true that a particle is the smallest possible vibration of a quantum field, then how does a particle acquire its (x,y,z,t) location (as we experience it in everyday life)? How do a large number of particles (as defined by a quantum field) come together in adjacent (x,y,z,t) co-ordinates in order to form an everyday object? How can we (as macroscopic beings) use our muscles to manipulate these quantum field particles in order to construct an everyday object? Intuitively, it seems that we would need some sort of laser beams or electron beams etc to manipulate a quantum field so as to move these particles to where would like them to be, in stark contrast to the reality that we can just pick them up with our hands and move them around.
Is it wrong for me to see the future of schools bleak? We have khan academy, 3b1b, The chemistry tutor, eddie woo and many thousand other people creating videos for basic topics (and even some complex ones, but for those base is important. And these people are great at creating that.) explaining things much faster, easier, free of cost and the best of all, visually, which I will admit is hard. Then we have people like arvin, minute physics, veratissium, and so many others who create amazing topics which even university students can benefit from. I only see a couple of decades before the smart people just stay in their house for studying. Therefore, I would like you to remember this. You people are doing something even better than many teachers. Because every youtuber uses atleast some years without getting any results. So thank you. Thank you very much. And I can somewhat understand why 'Ignorance is a bliss'...
Great video. Especially different breakpoints eg. Fe, Zr, Bi at which different processes take over (Super novae, weak force) to extend periodic table. Also note at end about Li, Be,B.m Great detail! Thanks! Would love further detail in a follow-up. Example C-N-O cycle & relative atomic abundances throughout visible universe. Wonderful. Thanks again.

as per the scientific theories we can see the pattern, first ions were created, as per expansion of the space those ions tends to lower their energy by surrounding the electrons (resulting an atom).. after creations of an atom, atoms further stabilized it to make molecules, and released the extra energy in universe to increase to entropy which shows the expansion of universe, but there will be some point when all the surrounding energy will be greater than individual matters and again matters will start to break and big bang occurs..
Outstanding. I am spellbound by your videos.
This is what we need to be taught in our chemistry classes in school.
Keep educating us.
Thank you so much
i’m studying nuclear engineering at university and i love seeing what this kind of video. what i learn in a class setting is shown in a more entertaining fashion, and is pretty on par with material. though that fancy process for heavier elements is called neutron absorption followed by beta particle decay. great video though super entertaining
Now I know why lithium, beryllium and boron is rare
Great! Like every video you do :)
Would it be possible for you to make an additional video covering the same topic, but from the point of view that the atoms are made up of particles that are vibrations in underlying quantum fields? That is, could you explain nucleosynthesis etc in terms of what is happening in the underlying quantum fields?
I would also greatly appreciate some guidance to the following additional but related question:
If it is true that a particle is the smallest possible vibration of a quantum field, then how does a particle acquire its (x,y,z,t) location (as we experience it in everyday life)? How do a large number of particles (as defined by a quantum field) come together in adjacent (x,y,z,t) co-ordinates in order to form an everyday object? How can we (as macroscopic beings) use our muscles to manipulate these quantum field particles in order to construct an everyday object?
Intuitively, it seems that we would need some sort of laser beams or electron beams etc to manipulate a quantum field so as to move these particles to where would like them to be, in stark contrast to the reality that we can just pick them up with our hands and move them around.
Scientists and science seekers should appreciate this simplification.
Arvin Ash is one of the best UA-camr
Excellent presentation 👏
Is it wrong for me to see the future of schools bleak? We have khan academy, 3b1b, The chemistry tutor, eddie woo and many thousand other people creating videos for basic topics (and even some complex ones, but for those base is important. And these people are great at creating that.) explaining things much faster, easier, free of cost and the best of all, visually, which I will admit is hard. Then we have people like arvin, minute physics, veratissium, and so many others who create amazing topics which even university students can benefit from. I only see a couple of decades before the smart people just stay in their house for studying.
Therefore, I would like you to remember this. You people are doing something even better than many teachers. Because every youtuber uses atleast some years without getting any results. So thank you. Thank you very much.
And I can somewhat understand why 'Ignorance is a bliss'...
Very good, thank you so much.
Your videos keep my brain working properly, thanks. ^_^
Thank-you Arvin !
loves the explanations!
Great video. Especially different breakpoints eg. Fe, Zr, Bi at which different processes take over (Super novae, weak force) to extend periodic table. Also note at end about Li, Be,B.m Great detail! Thanks! Would love further detail in a follow-up. Example C-N-O cycle & relative atomic abundances throughout visible universe. Wonderful. Thanks again.
