Nuclear Fission

To see all my Chemistry videos, check out
socratic.org/chemistry
In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy. There are also ways to modulate and soak up the neutrons.

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

[@117mady]

By which method we can insert neutron in the reacter

[@abdullah2.068]

Where do the two atoms released by nuclear fission go?

[@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.

[@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?

[@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.

[@amethystwings7337]

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

Hello

From where the Neutron comes

[@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!

[@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

[@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

[@elyadini98]

i'm soooo grateful for your videos,it feels that i understand everything in physics best feeling.

[@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.

[@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.

[@paramitaswarnakar6980]

Thank you very much Mr.Tyler. I'm very much impressed by your teaching. Your teaching is simply superb. your videos help me in many ways👍👍👍👍

[@jullyray7645]

Thank-you very much. I'm loving your great explanations.

[@sanmathirao2718]

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

[@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.

[@summerjohnson3452]

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

[@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!

[@herrington292]

Much more easily understood than any other video that I've seen. =).

[@ahmednawaz9406]

In a nuclear fission reaction we get a lot of energy,this energy comes from?bcz binding energy of Ba and Kr are lorger than urinium and law of conservation of mass is also obtain

[@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 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?

[@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.

[@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?

[@hg77777]

[@benb4805]

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?

[@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

[@HARSHVARDHAN-im2hb]

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

[@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.

[@Yazidn]

This was awesome! Thank you.

[@olstermanden]

this is amazing !

[@wittysparks6787]

how do you get spare neutron to start with ? And what happens to neutrons released which does not get Ur to hit ?

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..

[@kori4580]

Is the energy released transferred as kinetic energy of the resulting neutrons?

Thank you for making my favourite topic in a video

[@aggiesjc]

If anyone can help, what would that entity be that soaks up a few of the neutrons so the chain reaction doesn't get too out of control? Are there several substances that can do that? Is boron, like in a control rod something that does that?

[@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

if you could make a video or comment of some sort explaining the physic behind boosted-nuclear fission and why it can even split depleted uranium while conventional methods can not i would really appreciate it.

[@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

[@laibaadil2177]

so is it possible Mr. DeWitt that the released neutrons may hit krypton or barium and split them
