Nuclear Fission

[@samashakti]

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.

[@somethung8188]

well actually 9 but your point still stands

[@akshayesharma2778]

They take longer cuz there are alot of annoying kids that the teacher has to stop and deal with

[@somethung8188]

@Caesar just bc the original comment is 4 years ago doesnt mean i watched this 4 years ago my friend but wateva

[@abirmef9510]

[@117mady]

By which method we can insert neutron in the reacter

[@abdullah2.068]

Where do the two atoms released by nuclear fission go?

[@Versify-c7w]

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

[@Massimo1975Max]

I"m A 43 year old mechanic that understands visually.. If you Sir, were my teacher. I would not be a mechanic. Thanks so Much

[@tdewitt451]

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?

[@edwingaytos586]

What happen nuclear fission

[@tdewitt451]

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?

[@tdewitt451]

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.

[@PleaseReadBooks]

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.

[@sck479]

u are the best teacher. u explain difficult thing in a simple way. easy to understand. I appreciate your teaching.

[@hayleymcclure118]

I would agree

[@amethystwings7337]

I find this video helpful to me as I'm currently studying "Nuclear Decay" for A level exam :)

[@grantchang81976]

just fission

From where the Neutron comes

[@aathiraithevarajah5580]

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

[@SayuriRojas-l6f]

i recently just took one of my lab test and i kept getting 58 and under , after watching many of ur videos i did what i thought was never possible for me to ever get .... i ended up getting 100% not 95 not 85 not 75 ... 100% every topic i come to this channel hoping he has a video on it , he is truly amazing and hAS such a great way of explaining things as simple as he can without this guy i wouldve dropped out

[@summerjohnson3452]

THIS EXPLANATION IS SO MUCH BETTER THAN MY SCIENCE TEACHER. THANK YOU MR. DEWITT

[@solaimanwahab5286]

Amazing, taught me in less than 10 minutes while my teacher took 3 hours to explain this and half lives with no one understanding anything by the end

[@bingyang1091]

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.

[@brianoconnor1721]

Your videos are 1/3 of the reason I love chemstry, that says a lot

[@BlimeyGeezaMate]

Thank you very much for uploading this. It's useful for the nuclear physics module I'm currently doing. You've cleared a lot of stuff up!

Oh my goodness, this is the first video that actually made me understand fission, thank you so much

[@shishirr3103]

thank you so much for this, I just got awarded for making one of the best presentations on this topic!

[@clazzanator]

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.

nayana bandara yeh

[@toniatinsley9853]

Yess pleasee

[@Pierced777]

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 KZbin 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.

[@theramblingreviewer5150]

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!

[@finonevado8891]

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

I have a quiz tomorrw and a test Thursday with it covering this material... thank you so much for your videos! Thank you thank you thank you !

[@chakubanga1]

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..

[@glenntabar248]

I love the whole explanation of this topic, great information. Loved it!

[@ranashend6156]

Can you make another video on fusion reaction? cause I find it really helpful for me and thanks a lot for your efforts

[@erikamarasigan8966]

How do you find out how much Neutrons are released after the splitting?

[@bingyang1091]

the mass number before the split = sum of the mass numbers after the split.

[@johnp4871]

Great, simple explanation. Thank you!

[@triptidiyali3529]

[@pixxelwizzard]

Wow, that was so well explained and easy to understand. Thank you!

[@muhammadasghargul3003]

Sir wolud you tell me about the Neutron. From where the Neutron comes to Uranium 235?

[@andymtb5714]

That's what I was wondering too

[@вечная_мерзлота]

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?

[@tdewitt451]

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.

[@Rache-sx7lc]

You are the best teacher ever! Its sad that my teachers dont explain well like that

[@sanmathirao2718]

you explained this in such a simple way !!! :)

[@DavidMitchard]

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

Sir you are born for teaching the world

[@nk182]

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.

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💖👍👍👏👏

[@andymtb5714]

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!

[@HARSHVARDHAN-im2hb]

As usual another piece of art .

[@sukiinfinity5949]

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!

[@divyanshudembi4578]

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?

[@justnarmeen7027]

can you make video for nuclear fusion

[@alee_na-o8e]

I don't understand why are so less people waching ur video i mean the way u understand us everything very clearly

[@shreenidhhi8633]

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

[@calvinist34]

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.

Thanks! A great way of revising

[@cynthiacharles8825]

I love your presentation....even the lowest learner gets it quicker....so great👍

[@blossomrealsalvo2669]

[@zawarudo4459]

Hafnium can stop a chain reaction because of it property of neutron absorption and is used in nuclear control rods

[@jb372]

Great presentation and technique

[@juliecramer7768]

Finally an explanation I can understand . Thanks!

[@TerryClarkAccordioncrazy]

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?

[@AmmarTrades_]

May you stay happy sir !

[@TN_HondaDad]

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.

[@Nothing_to_write0]

This is the mass number of an atom which is the sum of neutrons and protons in the nucleus

[@minnrick7986]

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?

[@darby5987]

Enrichment isn't about nuclear reactions. It means separating the U-235 from natural uranium. Natural uranium is >99.2% U-238, 0.7% U-235 and

[@joshhh.228]

Your videos are helping me massively in science thanks a lot keep making them👍

[@fishywtf]

Thanks I had to re-read and watch the video again! Another question, if you made Cs unstable to the point it splits, would it be more powerful than a bomb with U inside?

[@xuancong1998]

Love the video. Can you make a video for Nuclear reactor ?

[@Jwhiterz]

OMG! thank you so much for this video! my physics exam is in 4 days! :D

[@selinvarghese7147]

@Haya Bangash 😅😂

[@fishywtf]

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?

[@litzyflores7018]

How do you know when Uranium will be split into those specific atoms ?

[@5556ttygrffgyghgf]

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
