Ionic
Bonding : The Strong elec trostatic fo r c e of attraction b e t we e n oppositely
charged ions .
Fac tors affecting ionic bonding : The ionic charge
-
the greater the charges , the
stronger the
bonding ( m o re is needed to ove rc o m e ).

:.
Generally the smaller the ion and the higher the charge,
the stronger the electrostatic attraction .
