Although there are far fewer nonmetal elements than metal elements, the nonmetals far outweigh metals in terms of abundance on Earth. This book looks at nonmetal elements from hydrogen (the lightest element) to the noble gases. It provides detailed descriptions of atomic structure, reactivity, discovery, sources, and uses for each element or group of nonmetal elements. This series describes the essentials of chemistry, from the fundamentals of atomic structure, through the periodic table, to descriptions of different types of reactions. The properties of elements are covered, as well as industrial applications for chemical processes.
