Required information
Two chloride ions and two sodium ions are in water, the "effective charge" on the chloride ions (CI¯) is −2.00 × 10-21 C
and that of the sodium ions (Na+) is +2.00 x 10-21 C. (The effective charge is a way to account for the partial shielding due
to nearby water molecules.) Assume that all four ions are coplanar.
