The Halogen Elements: Fluorine, Chlorine, Bromine, Iodine, Astatine (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. Discusses the halogen elements--fluorine, chlorine, bromine, iodine, and astatine--covering topics such as atoms, subatomic particles, how to find and refine halogens, and their uses in compound form Meet the halogens Atoms, subatomic particles, and the halogens Finding and refining the halogens Halogen compounds Halogens in our world The periodic table of elements. Describes the halogen elements, including how they combine with other elements and where they can be found in everyday objects This book explains the history, structure, characteristics, uses, and different compounds of halogen elements
