Ionic Compound

An ionic compound is a type of chemical substance formed when one atom (usually a metal) loses electrons and becomes a positively charged ion (cation), while another atom (typically a non-metal) gains those electrons and becomes a negatively charged ion (anion). These oppositely charged ions are attracted to each other, creating a strong electrostatic force that binds them together in a regular, repeating pattern called a crystal lattice. This structure results in compounds that are often solid at room temperature, with high melting points, and are typically soluble in water. Examples include sodium chloride (table salt) and magnesium oxide.
