Ion-ion bonds

Definition

Ion-ion bonds are the strongest type of intermolecular bond. They form between two ions of opposite charge, one positive and one negative, resulting in a strong attraction between them.

Ionic compound:

An ionic compound is formed when multiple ions come together through ion-ion bonds to create a stable structure. For example, table salt (NaCl) is an ionic compound made up of sodium ions (Na+) and chloride ions (Cl-).

Coulomb's Law:

Coulomb's Law describes the relationship between the strength of the ion-ion bond and the distance between the ions. It states that as the distance between ions decreases, the strength of the attraction increases.

Lattice Energy:

Lattice energy is a measure of the strength of an ionic solid. It represents the energy required to separate one mole of an ionic solid into its constituent ions in gas phase. Higher lattice energy indicates stronger ion-ion bonding within the solid.
