Interpretation: The reason for ionic compounds to be brittle needs to be explained.
Concept Introduction: An ionic compound is formed when a metal reacts with a non-metal. Here, metal is electron efficient and loses electrons while non-metal is electron deficient, thus, it gains electrons. In an ionic compound, metal has a positive charge and non-metal has a negative charge.
Answer to Problem 45A
Because of the strong bond present between ions.
Explanation of Solution
Ionic compounds are formed from positive and negatively charged ions. Thus, there is a strong bond between them due to strong electrostatic attraction. Due to this interaction between positive and negative charge, rigid lattice strictures are formed that create crystals. Brittleness is produced when pressure is applied because it causes the ions' alignment to move.Thus, ionic substances are brittle in nature.
