The structure of an atom is well known to me as something like this:

Structure of atom

But what is the accurate structure of the Nucleus ? What is the arrangement of the Protons and the Neutrons or any of the other nucleons? I will be glad if anybody give an image of its structure.

    $\begingroup$ @NeilRoy Have you also checked out the other content on that matter that can be found on Physics.SE, e.g. this question? If your question doesn't get a satisfactory answer on Physics.SE it is unlikely that you get a better one here, because your question is purely about physics not chemistry. Chemistry is concerned with molecules not with nuclei on a subatomic level. Maybe you could ask for clarification on Physics.SE. $\endgroup$ – Philipp Oct 12 '14 at 18:42

    $\begingroup$ @NeilRoy I'd suggest following some of the links in the Physics.SE question, including the "liquid drop model" $\endgroup$ – Geoff Hutchison Oct 12 '14 at 18:42

The nucleus is the very dense region consisting of protons and neutrons at the center of an atom.

The diameter of the nucleus is in the range of 1.75 fm ($1.75×10^{−15}$ m) for hydrogen (the diameter of a single proton)2 to about 15 fm for the heaviest atoms, such as uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electron cloud), by a factor of about 23,000 (uranium) to about 145,000 (hydrogen)

  • $\begingroup$ I wanted the accurate description of the nucleus with all the nucleons in it. Is it possible please? $\endgroup$ – NeilRoy Oct 12 '14 at 18:19
  • $\begingroup$ @NeilRoy Yes it is possible, but me I think it would be better some expert answer this question because I have just heard of stuff(quarks, etc) not read anywhere. $\endgroup$ – Freddy Oct 12 '14 at 18:29
