How many atoms are in an ionic bond?

Answer 1

There can be various amounts because molecules can form ionic bonds with other ions if they have opposite charges.

Answer 2

In an ionic bond, atoms transfer electrons to achieve a stable electron configuration. There is typically only one atom that loses electrons (cation) and one atom that gains electrons (anion) to form the bond. Therefore, in an ionic bond between two atoms, there are usually only two atoms involved.
