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??
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 ?
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??
loud , nice , clear, understandable. Thank you! you did much better than my physic teacher.
Mate you probably just saved med school for me, thanks heaps
Very helpful, much more concise and clear than the way my physics teacher taught it
thnkx so much sir... whenever I go through the RUclips for lectures u are the first choice of mine...
wow...This was so amazing lecture.. it was so explicit and understandable... I would expect more & more lecture from you .. thank u sir
awesme sir..!! a physics teacher like u is really required..!!

Exactly right :) Glad to see you got it!!!
Thank u Sir u are one of the best teacher I have ever seen

I'm so glad I watched this video~! *cries* really helpful! I hope I can do my report just like you did
amazing..I loved it👍👍
Amazing, thank you sir
dont mind but u looks same as *Louise de Broglie* .. great expln... love from india.
VERY HELPFUL! THANKS! YOU EXPLAINED IT SO WELL :D
awesome lesson keep it up man
Dude Y have u kept this in old phys playlist?... its the heart of modern phys
ur so smart my son
Thanks for all your lectures! Great help! Do you have a lecture on nuclear models? (liquid drop, shell model) thanks again!
Thank you. Sure :)
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??
Codo Sacho You have to study particle physics to answer that question :-) its something called strong nuclear force.
i know that i really get confused what is the differnence between strong force and nuclear binding force ??
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.
cool I'm planning to major in mathematics too :)
So if the mass is converted to binding energy to hold the nucleus together, how is it possible that fusion releases energy?

Good video, thanks!
Thanks😊
Thanks so much!
thanks for the help budd
glad you liked it
Wonderful
You got it sis ;)
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??
make sure you convert amu to kg before calculating E
Good call
lol I guess I know why I majored in mathematics :)
man very good video can we be friends
Excellent speaking.. still drink some less coffee
you spelled radiation wrong.. but great video!
why do i feel like watching porn after this lol
u saved my ass
