In the fall of 2006 it became number one on both the New York Times and Amazon.com bestsellers lists after Obama was endorsed by Oprah Winfrey.

Ionic Bonding. Ionic bonding is found in many ceramic structures such as NaCl, MgO and Al2O3. Atoms have unlike electrical charges, making them ions, which create an electrostatic attraction between atoms.This causes bonding between atoms. The ions pack into a regular arrangement.onic bonding is found in many ceramic structures such as NaCl, MgO and Al2O3.

Magnesium oxide, MgO. Higher melting point than sodium chloride: around 2,800ÂºC. This is because its Mg 2+ and O 2- ions have a greater number of charges, so they form stronger ionic bonds than the Na + and Cl-ions in sodium chloride.Because magnesium oxide stays solid at such high temperatures, it remains non-conductive.It is used for high-temperature electrical insulation.Page: 1  1. 2  2. 3  3.his is because its Mg 2+ and O 2- ions have a greater number of charges, so they form stronger ionic bonds than the Na + and Cl-ions in sodium chloride.
