  9. Mineral : single substance(an element or a compound) to form rocks 1)mineral of an element – Ag, Cu, Fe, Diamond 2)mineral of a compound – most of minerals, CaMg(CO3)2 (dolomite), CaCO3(Calcite)

  10. Five characteristics of minerals 1)solids 2)form naturally 3)never be a part of living things 4)definite chemical composition ex) CaSO4(gypsum) 5)the atom of minerals are connected to one another in an orderly, repetitive arrangement – crystal

  11. Groups of minerals 1)silicates(( )SiO) – most rock forming mineral 2)oxides – AlO, FeO 3)sulfides – CuS, ZnS 4)halides – NaCl(halite), AgI, ( )Br, Na2F 5)carbonates – CaCO3(calcite), CaMg(CO3)2(dolomite) 6)sulfates – CaSO4(gypsum)

  12. Minerals of silicates(( )SiO) 1)Ferromagnesian – significant amount of iron and magnesium, dark in color, bigger density2) Nonferromagnesianfeldspar – most abundant mineral, pink, white or gray quartz – common and various uses for industry
