How to the particles behave in the nucleus, are they stable or in constant motion?

Question

anonymous · Answer

mainly nuclions r stable, but bigger sized nucleus shows unstability... and emits rays as like $$\alpha ,\beta $$

anonymous · Answer

Yeahp.. it depends on the nucleus size..It is typical to say that particles in the nucleus don't move at all, but that's not absolutely correct.

are the protons more likely to be nearer to the surface then the neutrons?

anonymous · Answer

i don't know but i don't think so..Newtrons is like the glue of protons (because particles with the same charge sign are being stocked) so it's a valid hypothesis to say that newtrons are more likely to be nearer the surface of the nucleus.. but i am not sure..

unklerhaukus · Answer

and they like to pair up two protons and two neutron of opposite spin right/

anonymous · Answer

it makes sense but i am not quite sure :P

anonymous · Answer

You're asking for a classical description of something that is highly quantum.  The nucleons are "stable" in the same sense that the electrons of an atom are "stable" when the atom is in its ground state, and individual nucleons are "in orbit" around each other in the same way the electrons orbit the nucleus of an atom.  In fact, there is a shell model of the nucleus just like there is for the atom.

ah, what is the shell model of nucleus called?
