"Explains chemical bonding in terms of the electric interactions that cause the bonding in the hydrogen molecule. Shows the release of energy when H atoms combine to form H2 on a platinum surface, explaining that this energy change is related to the simultaneous attraction of electrons by two or more nuclei, opposed by Electron-electron and nucleus-nucleus repulsions. Uses animation to portray the quantum mechanical view of electron distribution and contrasts the bonding interaction between two hydrogen atoms to the very weak, non-bonding interaction between two helium atoms." - Summary from Worldcat.
