  • This video covers what radioactivity is, and in particular what alpha, beta and gamma emission is. I also cover the notation used to represent radioactive emission.

    Thank you very much, i surely won't be able to remember all but now i understand a little bit better what are radiations. I guess i'll come back to strenghen what i learn today.
    So i will be a little bit able to explain this to my children.

    Thank you for the video. I don't understand one thing, let's assume that we had atom with mass number of 3 and atom number of 2, and If we know that in the beta decay mass number stays the same and only atom number changes, does that mean that the nuclei of the atom will never get to the stable state and we will have indefinite decay ? (I am pretty sure that I am missing something)

    Hello sir
    In the alpha decay of uranium 238 the newly formed element is also short by 2 electrons. Where do these electrons go in the process?

    @yodustin00 Před 4 lety

    I have a question. How come all models of an atoms nucleus for the exceptions if a few very light particles like alphas, deuterium, & protium show the nucleus as a jumble mess kinda like a plum pudding model applied to the nucleus. I highly doubt that to be the case. I think it also explains way a helium nucleus is the standard alpha particle. What does the tritium nucleus really look like in a 3D model at what opposing angles are these baryons at in that case and does it scale. Is this the key to isotope stability?

  • @finnstadel
    @finnstadel Před rokem

    Random and spontaneous. Orbits are not random, but I guess they are pushed around by the vacuum fluctuations causing random event like radioactive decays. But where does this seemingly randomnes of the vacuum fluctuations really come from ? Is it comparable to brownian motion or the noise from electrons jittering around in a conductor ?

    Why is lead stable and realeses almost no radiation when number of neutrons is much more than protons

    • @j1n2
      @j1n2 Před 3 lety +1

      That's really a good question. after watching this video I think of 2 possible options:
      1) the amount of protons and neutrons in new Pb atom is just enough for a strong force to keep it together.
      2) It may be actually unstable for the first time but then there is some type of a gamma decay after so that in the end Pb will become a low energy Pb and then it's point 1 again - strong force can keep it together.
      I wonder how close am I though ?

    @5688gamble Před 6 měsíci

    People fear radioactivity too much. You respect it, like anything else. I imagine that since radiation is everywhere, that our bodies probably even depend on it to some degree, generating radicals and ionizing stuff, so if we isolated them from radioisotopes completely, might cells actually do worse or even get quite sick or die? Too little could be bad, much as too much is!

    Great video. I don't understand why the radiation is dangerous though? Don't we already have protons and neutrons in our bodies already? Why do these particles cause harm? Thanks.

    • @uramijajlovic5444
      @uramijajlovic5444 Před 2 lety +1

      Because the radiation can penatrate deep into our tissue, and cause harm to the very fragile DNA.material and lead to very bad mutations. It can cause, and as. we know of nowx it does cause cancerand overall is just very destabilizing for our body's natural way of functioning.

      I don’t see what’s wrong with the plot. It’s a graph of protons vs neutrons. For larger atoms, there tends to be more neutrons, so the graph will curve upward (since he has neutrons on the y-axis or vertical axis)
