Detailed Solution

An ionic compound is a chemical compound formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions). This type of bond is called an ionic bond.

Ionic compounds are generally formed when a metal loses electrons to become a cation and a non-metal gains those electrons to become an anion.
They are usually solid, crystalline, and have high melting and boiling points.
Most ionic compounds dissolve in water and conduct electricity in molten or aqueous states.

Examples

Sodium chloride (NaCl) – formed by transfer of an electron from sodium (Na⁺) to chlorine (Cl⁻).
Calcium oxide (CaO) – formed by calcium (Ca²⁺) and oxygen (O²⁻).
Magnesium chloride (MgCl₂) – formed by magnesium (Mg²⁺) and chloride ions (Cl⁻).
