4. Why are the elements in group 1, the alkali metals,
found only in compounds in nature?
Alkali metals are highly reactive metals. They react
quickly with other elements, such as oxygen. So, in
nature, they are found only in compounds.

6. The Elements of Life
More than 96 percent
of the mass of the
human body comes
from four nonmetals–
oxygen, carbon,
hydrogen, and
nitrogen.
