Okay, after thinking a bit more and harder, I understand a bit
more. 
Ok, anyway, now I understand that neutrons are needed to stabilize
the repusion inside the nucleus. ( Why are huh?
)
When the protons inside the nucleus increases, we need more and
more neutrons for stability right? There will come a point where no
amount of neutrons can make the nuclide stable. There are just too
many positive charges. Okay so we need nuclear binding energy (and
angular momentum?) to really hold the protons together. And
why due to the differences in neutrons no. and protons no. can
produce this nuclear binding energy leh?
The in bold one are my questions. Please help.
