Explanation:
An ionic bond is formed when one atom (usually a metal) donates its valence electrons to another atom (usually a non-metal) so they attain stable electron configuration. The two atoms become joined by electrostatic forces which result from the charges acquired by the atoms as a result of donating or receiving electrons.
An example is NaCl. Na (2.8.1) donates its one valence electron to achieve the stable configuration of (2.8.8) while CL (2.8.7) receives the electron to achieve stable electron configuration of 2.8.8. The Na is left with a positive charge while Cl is left with a negative charge. The two charged atoms attract each other and form an ionic bond.
