    Oh sure, that makes sense. Let me explain why. The entire point that Einstein made was that if you do the following calculations (mass of hydrogen) - (mass of constituent subatomic particles) = you will get a negative value! That negative value simply means that some of the energy (the absolute value of the negative amount) was transformed into nuclear energy that holds the protons and neutrons together. Hence, the energy mass equivalence. So in your case, what the book tried to do was show that

    The did the following calculation: (mass of tritium) - (mass of proton and 3 neutrons) = negative value. The negative value means that some of the mass energy must have been transformed into energy that holds the nucleus together. Let me know if that explains it.

    I suppose if you're only worried about the nucleus, you would not count the electrons. By the way, electrons are usually neglected because they have a very small mass to begin with, 1800 times smaller than a proton.

    can you tell me please in the nucleus the proton is attached to the proton although they repel so what force make them attach and why is proton is attached to the neutron although neutron is not charged??

    • @AKLECTURES
      @AKLECTURES  9 лет назад

      Codo Sacho You have to study particle physics to answer that question :-) its something called strong nuclear force.

    • @codosacho5924
      @codosacho5924 9 лет назад

      i know that i really get confused what is the differnence between strong force and nuclear binding force ??

    • @AKLECTURES

      Codo Sacho I suggest looking through my playlists in modern physics.

      It's the nuclear glue. But I myself don't know why they are glued.

  • @Daan87423

    So if the mass is converted to binding energy to hold the nucleus together, how is it possible that fusion releases energy?

  • @vaishnavisrinivas5109
    @vaishnavisrinivas5109 10 лет назад

    if i get the mass defect energy to be negative during alpha decay does it make sense .My teacher said that it can't be negative but i tried doing the question again for the binding energy and every time I get a negative value .Am i doing it right ?

    • @AKLECTURES
      @AKLECTURES  10 лет назад +1

      During an alpha decay, some unstable isotope breaks down into a more stable atom, in the process releasing the alpha particle as well as energy. That energy must be positive. If it was negative, that would mean that the initial isotope is more stable than the one produced. And if this was true, the alpha decay would not be likely to take place! Hope that helped!

    an unstable isotope become stable by alpha decay releasing one He particle and again do another decay! why they are not releasing all the energy at once and become stable??
