THIS ONLY TOOK YOU EIGHT MINUTES ! I was thinking why can't teachers teach this clearly? Then I was like maybe it's because they have a lot to cover in an hour and they don't have time to explain it as slowly as you .BUT YOU DID IT IN EIGHT MINUTES ,THAT'S EIGHT MINUTES OUT OF AN HOUURRRRRRRR that my teacher would have to take to explain this. I dunno. I just don't understand the way teachers think sometimes. YOU GAVE EXAMPLES AND EVERYTHING TOO! I just wanna thank you, THANK YOU you don't even understand how much you have helped me in my life.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
You said compounds with soak up the other neutrons... What are the names of the compounds that will soak up the netron.... I hope I'm asking this right
oh, sorry, i misunderstood your question. what i'm saying is that there are tons of other uranium atoms close to the one that has been split. so you split one uranium atom, and then it release neutrons that go and split the other uranium atoms that are close by. is that better?
good question! it's because an atom has to be really unstable (unhappy) in order to split. only Uranium is unstable enough to split. Ba and Kr or Rb and Cs are not unhappy enough, so Uranium isn't able to split them. make sense?
I have been watching your videos since seeing you on TED and though I am 25 now I noticed my brain had not retained much of my high school curriculum. These are helping me greatly in reminding myself of what I had learned but in a way that will stick. I am a very visual learner and your drawings are incredibly helpful. Just thought I would thank you for all of your videos.
you're right, it would be more powerful. however, it would be tough to do, because Cs is generally a pretty happy (stable) atom. but yeah, if you could make it extra unstable (maybe by adding a bunch of neutrons or something), than it would also want to split and release energy.
wow i was struggling an hour to figure out what happens in the nuclear reactor. and I was reading a lot of essays. but none of them are clear enough as your explanation. thank you for a wonderful understandable explanation
we're not try to split U-236, we're trying to split U-235, and U-235 is fissile. U-236 only exists for a fraction of a second, until it breaks apart. if you can shoot neutrons into something and split it, it's fissile. we shoot neutrons into U-235 and it splits, so it's fissile. we never shoot neutrons into U-236; it splits on its own.
Great video, thank you. I will use it in my class. For those who say why my teachers can't teach this well, you need to keep in mind that most teachers don't have time to plan this well. They have to teach 5 classes a day, being interrupted by undisciplined kids, grade more than 100 assignments, enter grades and attendance in some database, deal with parents, attend meetings, do paperwork required by regulations and laws that mean well but don't help. There is no time to think and prepare for classes.
Dude.. If this is how Science was taught from the day when Human learned to make fire, Humanity would have flourished.. Nonetheless, thank you kindly Tyler DeWitt, I was smart in school, but ran away, only to learn at this age... And Sincerely you have made education as simple as this video.. I may not get to work as a Nuclear scientist, but I can assure you one thing.. Not a Human scientist will ever look down at me, when it comes to explaining fussion.. I sincerely bow to your ability to inform..
Really thank you so much u r super talented in explaining this stuff and u make all of the chemistry lessons super easy keep it up please cuz the world needs someone like u in order to understand chemistry💖👍👍👏👏
My textbook was pretty good, so I already understood, but I just have to say that after having watched a few of your videos I am definitely a fan. You have got yourself a new subscriber!
Great videos! I've watched aout 10 of them already and I feel like I know more in an hour of watching these videos than in the past 3 weeks, where our teacher has been rambling on about random shit! Thank you so much. You are a life saver.
Thanks for the helpful video for amateurs in physicochemistry like myself, Tyler. Just wanted to ask, thinking of Binding E, if BE is needed to split the nuclei of stable atoms and equals the Mass defect. Then, if nuclear fission is where the unstable nucleus splits into compounding elements and yields energy, does this mean that the yielded E equals a mass defect meaning the total mass of the nuclear waste is smaller than the mass of the unstable atom before decay and the difference being the yielded E? Cheers.
This was an amazing video! Clear, simple, easy to understand. What I'm wondering now is: what happens to the "daughter" atoms that result from the neutron hitting the original atom? Are the daughter atoms able to further be split into more atoms if a neutron hits them (although that wouldn't make sense because they are already stable)? Will they keep gaining neutrons until they are unstable again, and thus, make it so they can be split again? Or do they simply not matter after the atom is split? I'm also wondering where the neutron that splits the original atom in half comes from in the first place. Thanks!
I wanted to sleep, but then I discovered your channel. And THEN I see that you're no longer making these videos. I did not ask to participate in such rollercoaster of emotions m8
Tyler doesn't make videos anymore from a reply of his in another video. He told the subscriber that if he wants him to make more videos, to drop him some coin on his support pages. $100k/year on RU-vid is not enough for a man of his intellect. At a minimum, he could work as a responsible health physicist at a nuclear plant and make $200k easily with no sweat off his back from just the knowledge in a few of his nuclear physics videos alone. Then he would make more money and still have more time to watch videos than the countless hours it takes making them for peanuts. He does teach extremely well though I must say.
You never said where is that one proton coming from. You started explaining the process from half the way. Protons don’t just exist out there by themselves waiting for uranium atom to capture them. do where's it coming from? what's the exact process?
How soon do the electrons coalesce around the newly formed fission products? Do they follow the nuclei as they fly apart or is there a sort of cloud of free electrons which eventually end up balancing out the positive and negative charges?
in nuclear fission, an atom/isotope of an atom splits up into any atom ( will 1 less atomic number,same mass) an electron and matter like (V) this occurs in nuclear fission of 12N7
Thank you so much sir. You are very great at what you're doing. Thanks again for the efforts that you put in your videos. You make chemistry learning a wonderful experience. The believe in you for almost all my chemistry doubts..❤❤
Hi! Can you please make a nuclear fusion video please? Whenever I needed help in science you always got me, and everyone else too. I think everyone is very lucky to have you explain many different science units!
THREE questions.... 1) From where does the one neutron come up? 2) In which circumstances does the Uranium 236 split into by products other than krypton and Barium? 3) How does the one neutron get into the nucleus of the Uranium 235, if it doesn't, then where does it go?
Because when the uranium 235 nuclei splits the spits means the right amount of protons and neutrons to make krypton 92 and barium 141 and then 3 nuetrons are also given off
When you described U-236 splitting into those three different combinations, were you stating that there are many different ways to split U-236 or that U-236 always splits into one of those three combinations?
Hi nice vids . Just wanna ask 1. Where was the initial neutron could come from if where talking actual application 2 why are there unstable elements how about U238 why is it stable unlike 235
What I found confusing was that you didn’t explain that the actual amount of neutrons is 143 in U 235 not 235 if I am correct? At least I found it a bit confusing until I had to look it up. Idk, maybe others were a little confused on that? I am a numbers guy and was doing the math and had to know how you were getting the numbers. Maybe touch briefly what the numbers mean in the beginning? Great video nonetheless that was a quick n dirty explanation without getting too deep.
Very helpful video as well as your videos on beta minus, beta positive, and alpha decay. You didn't go into this but there is a difference between fissile and fissionable materials. U235 is fissile, U238 is fissionable. Looking forward to your video on anti-matter. Looked for it but didn't see it.
Great stuff, thank you(!) and a question.. Regarding the limiting of the amount of Uranium in order to control how many reactions occur and how much energy is therefore released, is that the same thing as enrichment? More enrichment = more reactions = more energy?
HAello, im new to Nuclear Fission so i have one question: If uranium creates kr and ba, where does the other pieces of uranium come from? Is it true that if you only hit one uranium atom that the atom is splitting but the rest of the urannium doesnt split? And gets hit later by neutrons? (My english isn't good)
awesome video, quick question, the first neutron which results in the fission, where does it come from? How do scientist initiate the reaction to fire the first neutron? thanks
When you split the U, it'll yield maybe Ba and Kr, but you said," U will split more U"... Why doesn't it split Ba and Kr or Rb and Cs after the first splitting of U?
I thought that neutrons would actually stabilize the nucleus though, not cause it to split. Don't the neutrons "hold the nucleus" together/act as a buffer for the protons, preventing the protons from repelling each other too much?
It totally depends. The balance of protons and neutrons has to be right. If the balance is good, then yeah the neutrons hold the nucleus together. If the balance is off, then the neutrons disrupt the balance and the atom wants to split. Now maybe you’re wondering, what is the correct balance of protons and neutrons? It’s different for every atom, so it’s not something you can easily predict. However, check out the “Band of Stability” if you want more information about this topic.
