You would not guess that they contain shiny metal. The earth's crust is made up of many minerals. Minerals can be defined as naturally occuring chemical elements and compounds. People have discovered more than 2,000 different minerals. Many of these contain metals. But because the metal elements are linked with other elements in the minerals, the metals do not show all of their properties. Figure A 1. Most minerals are elements, compounds 2.
