  1. List the 20 elements that are considered native minerals. Look at the periodic table and write down their symbol.

  1. What are the elements the make up the following mineral families?

A. carbonate

B. sulfate

C. sulfide

D. silicate

E. oxide

F. borate

  1. Fill in the chart below. Look at the previous lab for the formula. Write out the elements name. For example Calcite is CaCO3, the chemical family is "carbonate" and the elements are calcium, carbon, and oxygen.
