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.

The dynamic interactions of water molecules. Individual H2O molecules are V-shaped, consisting of two hydrogen atoms (depicted in white) attached to the sides of a single oxygen atom (depicted in red). Neighboring H2O molecules interact transiently by way of hydrogen bonds (depicted as blue and white ovals). Strong linkagesâcalled covalent bondsâhold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atomsâin this case oxygen and hydrogenâshare electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H 2 O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
