Repartition of n's and p's in nucleus

[Joans]

How do protons and neutrons behave in nucleus? Is they just sit where? Or move some how?
or maybe jei form some form constant to that nucleus, like in solid state materials atoms forms crystal grating( I do not know how to call it in English).
Maybe protons is more found in outside nucleus than inside because of electrons effect?
Or maybe it stays the same as been formed and hold some information?

You have to go to quantum mechanics, just as the electrons in an atom neither sit still like raisins in a cake, nor circle around like planets around the sun, but they are distributed with position and momentum with probability function governed by the Shcrödinger equation (in the non relativistic treatment), google "the shell model", the protons and neutrons form shells in ENERGY space, but they have probability distribution functions (wavefunction) very similar to the atoms (google hydrogen atom wavefunctions) to see how they look)

And yeah, regarding language; Crystal LATTICE (not gratings hehe) :-)

The repartition of n's and p's in the nucleus is not a random distribution. Protons and neutrons behave differently in the nucleus due to their different properties. Protons have a positive charge and are attracted to the negatively charged electrons, while neutrons have no charge and do not interact with the electrons. This results in protons being more likely to be found closer to the edge of the nucleus where they can interact with the electrons.

However, both protons and neutrons are constantly moving within the nucleus. This movement is not chaotic, but rather follows certain patterns and arrangements. Similar to the way atoms form a crystal lattice in solid state materials, protons and neutrons also form a stable structure within the nucleus. This structure is known as the nuclear shell model, which explains the behavior and arrangement of protons and neutrons in the nucleus.

As for whether the distribution of protons and neutrons in the nucleus can change, it is possible for a nucleus to undergo nuclear reactions and change its composition. However, the overall structure and arrangement of protons and neutrons in the nucleus remains relatively constant and holds important information about the element and its properties.
