Fill in the blanks: The interactions between particles can be described by Coulomb's law: that is, the between two charges has the least effect on the forces between them. Additionally, in an atom, the distance between the valence elctrons and the nucleus, knonw as the , has the greatest effect on the force. Finally, as the atomic radius decreases, the increases.
