The structure of a sodium chloride (table salt) crystal is shown in the figure below. Each sodium ion Na+ has a charge +e and is adjacent to a chloride ion Cl−, which has a charge −e. The electric force of attraction between sodium ions and chlorine ions holds the crystal together. Suppose you attempt to break a cubic salt crystal, 1.26 mm on a side, by applying forces F and −F perpendicular to opposite sides of the cube, trying to...
