Sodium chloride ionic bond

An ionic bond is a chemical bond where electrons are taken from one atom and given to another atom in a molecule. This creates an electrostatic attraction between the positively charged ion and the negatively-charged ion. Chemicals with ionic bonds tend to be high-melting solids that are crystalline. Many of them dissolve in water.

A chemical bond cannot be seen as completely ionic or completely covalent. There is no sharp boundary between ionic bond and covalent bond.[1] It can be seen as predominantly ionic, where the electron stays at one atom most of the time, or predominantly covalent, where the electron stays at both atoms for almost equal amounts of time.[2]
