The Halogen Elements
Understanding the Elements of the Periodic Table
The Halogen elements are among the most reactive on the periodic table--and in their natural forms, they are highly poisonous. Halogens are used for a variety of purposes, including the sterilization of water and making disinfectants. This book chronicles the efforts of brave scientists to discover and isolate these elements, examines compounds formed by halogens, and takes a close look at their atomic structure.
