    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.

  • @tdewitt451
    @tdewitt451  12 лет назад +8

    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.

    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.

  • @tdewitt451
    @tdewitt451  12 лет назад +9

    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
    @tdewitt451  12 лет назад +10

    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?

    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.

      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 RUclips 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.

    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.

      Cesium is 144 or 143 it's about the equation in my book the equation is : 235,U,92 +1,n,0 - - - - >236,U,92 * - - - > 144 Cs 55 + 90 Rb 37 + 2(1 n 0) + Energy , instead of Tyler's : 235 U 92 + 1 n 0 - - - - > 236 U 92 * - - - - > 143 Cs 55 + 90 Rb 37 + 3(1 n 0) + Energy , xenon is the same make it 144 Xe 54 and its neutrons 2 (1 n 0) , so that depends on changing the number of neutrons in the equation that's why you find different numbers many times, HINT: the sign (*) indicates that the nucleus of this element is unstable and decayed rapidly. Hope you understand, Good Luck.

    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!

    @tb2748 5 лет назад

    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?

    • @tdewitt451
      @tdewitt451  5 лет назад +1

      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.

    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?

      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

    why does uranium split into krypton and barium, and not some other elements?

      Sorry, correction to my question: Is there a limit to how many different ways uranium can split? Also, are there always going to be 3 neutrons at the end?

    Don't most of the elements that are made from fission have much, much shorter half-lives than Uranium235? My understanding is that means they are less stable than the Uranium, not more stable...?
