They're a long way away from being able to actually simulate a whole nucleus. View solution. J.J.Thompson carried out his cathode ray tubes experiment and found out that all atoms contain negatively charged particles called electrons. Though isotopes are identical, some isotopes can transform into a different element. Error bars are shown for all data and represent statistics plus point-to-point systematics (but not not systematics that would shift all the data for a single nucleus). To do this, he decided to carry out an experiment and made fast-moving particles (alpha particles ) fall on a thin gold foil. That translates into the fact that the nucleus takes up 3 What is the approximate size of an atom?

This is almost all the The cookie is used to store the user consent for the cookies in the category "Analytics". A larger chunk of fast-moving alpha particles passed straight through the gold foil without any deflection. Since most particles passed through the gold foil, most of the atom is an empty space. I can't give you a real answer but I figured this may be better than nothing: Because the interaction energies inside the nucleus are very low, and when we perform experiments on nucleons at those energies they behave primarily as discrete particles. 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.
