Explain an example of a chemical bond

Ionic bonds are formed by the electrostatic attraction of atoms that have opposite charges ... Sodium chloride, or NaCl, is an example of an ionic bond.

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
