Smaller ions with higher charges create stronger bonds. Understanding the physical characteristics of ionic compounds provides insight into their behavior in industrial processes, natural geology, and biological systems.
Why Ionic Compounds Are Hard Yet Brittle Under Pressure
Brittleness Under Pressure Despite their hardness, ionic crystals are brittle. When stress is applied, layers of ions may shift slightly, causing like-charged ions to align and repel each other.
Unlike molecular substances held by weaker intermolecular forces, ionic bonds create solids that are typically hard, brittle, and exhibit distinct patterns in melting point, solubility, and electrical conductivity. Crystal Structure and Hardness Every ionic compound forms a crystal lattice where each ion is surrounded by oppositely charged ions in a highly ordered three-dimensional array.

This thermal stability makes them suitable for high-temperature applications. The polar water molecules surround the individual ions in a process called solvation, which overcomes the lattice energy holding the solid together.
