Viewers will see that chemical bonds are the key to understanding how elements combine. The differences between ionic and covalent bonds are clearly presented using vivid graphics and dynamic footage. Students see how valence electrons interact among atoms to form compounds, and learn how simple Lewis structures can help describe how easily an element will react. Students explore the significance of the arrangement of the elements and are shown how to predict the behavior of an element from its position on the periodic table. Includes a look at some of the many patterns found in periods and groups of elements that combine to create the world around us. Features information about a printable "Guide to the Elements" that can be used for student research and assessment purposes.
