Represents a crystal a crystal unit of cesium chloride (CsCl).
The Cs atoms are situated at the corners of a cube of side 0.4 nm, whereas a Cl atom is situated at the centre of the cube. The Cs atoms are deficient in one electron, while the Cl atom carries an excess electron. Suppose that the Cs atom at the corner A is missing. What is the net force now on the Cl atom due to the seven remaining Cs atoms?
