Question

How does the lattice energy for an ionic solid relate to the size of the ions in the ionic solid? O Lattice energy becomes less exothermic (less negative) with decreasing ionic radius. Lattice energy becomes more exothermic (more negative) with increasing ionic radius. O Lattice energy becomes less exothermic (less negative) with increasing ionic radius. Lattice energy is unrelated to the size of the ions. How does the lattice energy for an ionic solid relate to the magnitude of the charge of the ions in the ionic solid? Lattice energy becomes less exothermic (less negative) with increasing magnitude of ionic charge. Lattice energy becomes more exothermic (more negative) with decreasing magnitude of ionic charge. O Lattice energy is unrealted to the charge of the ions. O Lattice energy becomes more exothermic (more negative) with increasing magnitude of ionic charge.

Answer 1

Ans: - According to Born lande equation ALH = k1Z+112-1e²M NA ALH & 7z+]]Z_] charge on ion. ALH a l Radius of Cation and 8448- Anion. So-> Lattic energy becomes less exothermic (less negative) with Incresing ionic radius. ALH & ! 8+r A Lattic energy becomes more exothermic (More negative) with Incresing Magnitude to Jonic charge ALH & 1Z+/1 Z-]
