Solution

Solution Steps

Step 1: Understanding Crystal Lattice Energy

Crystal lattice energy is a measure of the strength of the bonds between ions in a crystal lattice. It is the energy released when gaseous ions come together to form a solid crystal lattice. This energy is a reflection of the electrostatic forces between the ions.

Step 2: Analyzing the Options

Option 1: "It increases as the size of the ions increases." This is incorrect because larger ions have a lower charge density, leading to weaker electrostatic forces and thus lower lattice energy.
Option 2: "It increases as the charge on the ions decreases." This is incorrect because higher charges on ions result in stronger electrostatic attractions, leading to higher lattice energy.
Option 3: "It is the energy that ions absorb when they form a crystal." This is incorrect because lattice energy is released, not absorbed, when a crystal is formed.
Option 4: "It is a measure of the strength of the bonds between ions." This is correct as lattice energy quantifies the strength of the ionic bonds in the crystal lattice.
