Summary: This program begins with an examination of atomic structure-presented in terms of protons, neutrons, and electrons-and the idea that bonding is related to the filling of electron shells to create more stable particles. Examples of metals and their usefulness are presented, and the relationship between properties and structure is examined. Other processes demonstrated include the formation of...

Summary: A second product made from sodium chloride, sodium metal, is also produced at the chemical plant shown in Chemicals from NaCl: 1. It is formed by electrolysis of a sodium chloride, calcium chloride molten mixture, and is isolated at the cathode of the cell as a liquid. This product is extremely reactive; it must be handled very carefully and packaged in an inert oil, free from air and moisture....

Summary: Earth, air, fire, and water: according to some ancient theories, these four elements made up the cosmos. Beginning with the work of the Greek philosopher Democritus, this Science Screen Report describes how an accurate atomic theory developed and led to awareness of a wide variety of elements. Specific examples showing different configurations of these basic units of matter-including graphite...
