What you learn in Theory:
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) to about 15 fm for the heaviest atoms, such as uranium.
What you learn in Practice:
The principle of the conservation of energy is used to calculate the distance of closest approach as a measure for the size of a nucleus
