Answer :
Ions in ionic compounds create a lattice by strong electrostatic forces of attraction. They therefore exist at normal temperature as solids.
A chemical compound known as an ionic compound in chemistry is one that contains ions bound together by the electrostatic forces known as ionic bonding.
Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.
These can be either polyatomic species, like the ammonium (NH+ 4) and carbonate (CO2 3) ions in ammonium carbonate, or simple ions, like the sodium (Na+) and chloride (Cl) in sodium chloride. Since individual ions in an ionic compound typically have more than one nearest neighbor, they are not thought of as belonging to molecules but rather as components of an ongoing three-dimensional network.
When solid, ionic substances typically have crystalline structures.
