All substances are composed of one or more of approximately 100 elements.
5.2.8.A.2. Analyze and explain the implications of the statement ''all substances are composed of elements.''
Substances are classified according to their physical and chemical properties. Metals are a class of elements that exhibit physical properties, such as conductivity, and chemical properties, such as producing salts when combined with nonmetals.
5.2.8.A.6. Determine whether a substance is a metal or nonmetal through student-designed investigations.
