An ionic bond is a chemical link between two atoms caused by the electrostatic force between oppositely-charged ions in an ionic compound. There is an ionic bond between the sodium and chloride ions in table salt, NaCl. A chemical bond formed between two ions with opposite charges. Ionic bonds form when one atom gives up one or more electrons to another atom. The simplest compounds which form Ionic Bonds are those that result from an exchange of electrons between Metals (Groups IA, IIA and IB through VIIIB of the Periodic Table) and the Halogens (Group VIIA). Elements consist of neutral atoms or molecules, the electrical neutrality is because the number of positive protons equals the number of surrounding negative electrons in their respective energy levels. Charged particles called IONS are atoms, or groups of atoms, which have lost or gained electrons to have a overall net electrical positive or negative charge.
An example of ionic bonding is Sodium Chloride, or table salt. Sodium has one spare electron in the outer shell, and Chlorine has an outer shell that needs one electron to complete it. They can therefore react to form an ionic compound. Another example is Potassium Iodide, that is used to dissolve gold.
