← ScienceWhich consequence results when ionic crystal size decreases?
A)Lattice energy becomes more negative✓
B)Melting point becomes immeasurable
C)Solubility in solvents decreases
D)Conductivity decreases to zero
💡 Explanation
Decreasing crystal size in ionic compounds increases surface area, increasing electrostatic interactions reflected in the crystal's lattice energy; because the ions are more strongly held at the surface, lattice energy becomes more negative rather than a decrease because there's more force at the surface rather than inside the crystal.
