The masses of other atoms go up to about 200 times this. Similarly, the box representing the nucleus is provided by the strong nuclear force between protons and neutrons that hold them all in place. Through this experiment, humankind became aware of the existence of atomic nuclei. But why is this so? Protons and neutrons are complex composite particles with many internal (and external) interactions, so their wavefunctions will tend to be much more localized than those of electrons. Use this info and the particle in the box model to make an order of magnitude estimate of the ratio $$\frac{\text{size of atom}}{\text{size of nucleus}}$$. I used the nm to fm conversion and ratio and got 1/100000 which is basically nucleus/atom or 1 fm / 100000 fm but this wasn't right and I got mixed up here.

A big part of what they do at Jefferson laboratory is to search for the change between nucleon--meson degrees of freedom (as reasonably well described by quantum hadrondynamics) and quark--gluon degrees of freedom (as described by quantum chromodynamics); but even the on-set of QCD dominated behavior does not correspond to quark--gluon plasma which occurs at much higher energies. About 5 million hydrogen atoms could fit into a pin head. 105. The "box" is provided by the confining electromagnetic force exerted by the nucleus on the electron. The size of atomic nucleus is quite small in comparison to the atoms size. Mostly the shape of the nucleus is spherical or oblong. The size (volume) of the nucleus is tiny compared to the size I don't know of any better model, although I'm not an expert in nuclear physics so I can't be sure one doesn't exist. **Size: **Atoms have an average radius of about 0.1 nm.
