Ionic
Bonding is important in Ceramics and involves non-directional bonding between
atoms of different size. |

Many
ionic compounds have anions (-) that are larger than the cations (+) in
the structure.
· The
lowest Madelung energy occurs when the cation (+) is surrounded by as many
anions (-) as possible consistent with structural stability
· Pauling's
Stability Rule provides guidelines to the allowed structures based on the
ratio of anion to cation radius. |
