"Begins by describing the basic structure of atoms and how ions are formed as atoms gain or lose electrons. Molecules and the covalent bonds that hold them together are then investigated. The program then explains the difference between organic and inorganic molecules, polar and non-polar molecules and how the hydrogen bonds that form between polar H2O molecules provide water with a number of unique characteristics critical to life. A look at the concept of pH and the role of buffers concludes the program."--Container.
