👉 Coordination in chemistry refers to the physical connection between two or more molecules that have the same functional groups, leading to the formation of a diatomic or polyatomic ion. This process involves the sharing of electrons between atoms, creating a stable, neutral entity. For example, when sodium chloride (NaCl) forms, the positively charged sodium ion (Na⁺) and the negatively charged chloride ion (Cl⁻) are held together by ionic coordination, where the electron pairs from Na⁺ are shared with Cl⁻, resulting in a strong electrostatic attraction that holds them in a crystalline lattice. This coordination is crucial for the stability and properties of many compounds, influencing their reactivity, solubility, and physical states.
