Bonding, Electronegativity , & Bond Shape

Bonding, Electronegativity , & Bond Shape. Forming Chemical Bonds. According to the Lewis model an atom may lose or gain enough electrons to acquire a filled valence shell and become an ion. An ionic bond is the result of the force of attraction between a cation and an anion.
