Ionic compound
In electrostatic forces termed ionic bonding. the compound is neutral overall, but consists of positively charged ions called cations as alive as negatively charged ions called anions. These can be simple ions such(a) as a sodium Na+ in addition to chloride Cl− in sodium chloride, or polyatomic quality such as the ammonium & carbonate ions in ammonium carbonate. Individual ions within an ionic compound usually pretend house nearest neighbours, so are non considered to be factor of molecules, but instead element of a non-stop three-dimensional network. Ionic compounds usually pretend crystalline structures when solid.
Ionic compounds containing basic ions acid–base reactions. Ionic compounds can also be presents from their module ions by evaporation of their solvent, precipitation, freezing, a solid-state reaction, or the electron transfer reaction of reactive metals with reactive non-metals, such(a) as halogen gases.
Ionic compounds typically have high melting and boiling points, and are hard and brittle. As solids they are almost always electrically insulating, but when melted or dissolved they become highly conductive, because the ions are mobilized.
