... each atom, there is no electrostatic force between the two. On the other hand, if one object is charged with an excess of protons (deficiency of electrons) and the other an excess of electrons, there ... is in the order of one-millionth (10 –6 ) millimeter, and the nu- cleus, one-millionth of that. These typical figures emphasize the minute size of the atom. 1.2 Elec...
