2.
A sodium chloride molecule has an Na-Cl distance of 236.1 pm (recall 1 pm is 10-12 m.) In this ionic molecule, the effective
charges of the ions are +1.3x10-19 C for the Na and -1.3x10-19 C for the Cl (the charge is a little less than the charge of an
electron because the chlorine doesn't remove the electron from the sodium completely, sharing it just a little bit.)
