What determines lattice energy?
Understand the Problem
The question is asking about the factors that influence lattice energy, which is the energy released when ions in the gaseous state form an ionic solid. It seeks to explore the key concepts that affect this energy, such as ionic charge, ionic size, and the arrangement of ions in the lattice.
Answer
Magnitude of charges and distance between ions
The primary factors determining lattice energy are the magnitude of charges on the constituent ions and the distance between the ions.
Answer for screen readers
The primary factors determining lattice energy are the magnitude of charges on the constituent ions and the distance between the ions.
More Information
Lattice energy increases with higher charges on ions and decreases with increasing distance between ions. This is because stronger ionic bonds release more energy when formed.
Tips
Common mistakes include ignoring one of the two factors (charge and distance) and not considering both in tandem.
