The Foundations of Chemistry

OO

nly about 20% of the elements are classified as nonmetals. With the exception

of H, they are in the upper right-hand corner of the periodic table. In this chapter

we shall consider the chemistry and properties of nonmetals and metalloids that

illustrate group trends and individuality of elements within groups of nonmetals.
