An ionic bond is the electrostatic attraction formed between (+) cations and (-) anions. The cations and anions are formed when a non-metal (high EN) steals an electron from a metal (low IE). This transfer of electrons gives each atom a filled valence shell (stable octet) of electrons. glycolysis biochemistry
