The nucleus has a diameter 10,000 times smaller than the atom. According to quantum mechanics, The mass of the box itself does not affect the energy of the particle inside it: the only thing that matters is the length of the box. The Atomic Diametre of an atom is about 10 metres. Rutherford wanted a very thin sheet for his experiment, and gold foil could be pounded into sheets of only 0.00004 cm thickness. Did Jefferson say the constitution should be rewritten? The formula to measure the size of nucleus is: R = R0A1/3 Where R0 = 1.2 * 10-15 m Density of Nuclear Matter The density of a nucleus () is its mass divided by the total volume. 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.
