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.) 2 A* a. b. C. d. e. 1mm Na Cl 1mm Find the dipole moment of the NaCl molecule. What is the magnitudes and directions of the electric force on a proton placed at each of the locations of the test points, A and B? *B What is the magnitude and direction of the electric force on the molecule and due to a proton placed at test point A? How large (magnitude) is the potential difference between two points in line with the molecule, as shown below, where point A is 1 mm from the Na and point B is 1 mm from the Cl? Is the potential higher at A or B? Provido physica
