An ionic bond is formed by the complete transfer of some electrons from one atom to another. ... When the transfer of electrons

occurs, an electrostatic attraction between the two ions of opposite charge takes place and an ionic bond is formed.

Why do ionic compounds bond?

Ionic bonds result from the electrostatic attraction between oppositely charged ions, which form when valence electrons are transferred from one atom to another.

How does bonding occur?

Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.
