Ionic bonds involve the transfer of electrons between atoms to achieve stability by filling their outer shells.
An ionic bond is a type of bond that joins ions. Atoms with more than one shell are most stable when the outer shell contains 8 electrons. During an ionic reaction, atoms give up or receive electrons to ensure a stable outer shell. In the formation of the compound NaCl, sodium will donate one of its outer shell electrons. Chlorine will then accept the electron, leaving both atoms with an outer shell of 8 electrons.
