Definition of Lattice Energy
The definition of lattice energy is the energy released when ions in a crystal lattice are formed from their respective gaseous ions. This concept plays a crucial role in understanding the stability of ionic compounds.
The magnitude of lattice energy is determined by the charge impact of the ions and their distance from each other in the crystal lattice. Higher charges on ions result in stronger electrostatic attractions, leading to higher lattice energy values. Additionally, as the distance between ions decreases, the lattice energy increases due to the stronger interaction between the opposite charges.
It is important to note that there is a direct correlation between lattice energy and the strength of the ionic bond. The higher the lattice energy, the stronger the bond between ions in the crystal lattice.
