So, for example, if we have two atoms that are distance D apart and these atoms are stationary and atom one has a partial positive charge, and atom two has a partial negative charge, then these two atoms will attract each other as a result of that attractive electric force, now, because these are assumed to be stationary, that force is electrostatic. And the equation that gives us the magnitude of that electrostatic force is Coulomb's equation. So the electrostatic force between the two charges is equal to So the numerator is the product of K. A constant. Q one, the charge of atom one and q two, the charge of atom two. And the denominator is simply the square, the distance between the center of masses of those two charges. So we see that the larger the charge is, the greater the numerator is and the greater the tractive force is.
