SUMMARY
The discussion focuses on calculating the electrostatic force between sodium ions and chloride ions in solid sodium chloride (NaCl). Participants confirm the use of Coulomb's Law, expressed as F = k(q1*q2)/r², where q1 and q2 represent the charges of the ions, specifically the charge of an electron (1.602 x 10^-19 C). The separation distance between the ions is approximately 0.28 nm (2.8 x 10^-10 m), leading to a calculated force of approximately 2.9 x 10^-9 N. Clarifications regarding the charge states of the ions are also addressed.
