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. The smallest nuclei are approximately 1 m in diameter and are found in yeast cells. Each atom has an order of magnitude of 10 -10. >. Similarly, the box representing the nucleus is provided by the strong nuclear force between protons and neutrons that hold them all in place.

The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. Give an order of magnitude estimate for the length of a molecule of dodecane. Michael Faraday coined this term in 1844 when he was trying to describe the centre of an atom. The size of atomic nucleus is quite small in comparison to the atoms size. R = R 0 A 1 3 Where R 0 = 1.210 -15 m. From the formula, we can conclude that the volume of the nucleus, which is proportional to R 3, is proportional to A (mass number). The order of magnitude of nuclear energy is 1MeV whereas the energy of atomic energy levels is of the order 1eV. An atom is a million times smaller than the thickest human hair.
