How would you try to identify your mineral? If you were a mineralogist, you would use certain properties to identify the mineral. You can observe some properties by looking at the mineral. For example, you can see that the mineral in Figure 3.12 is the color of gold and is shiny. But, you cannot see all mineral properties. You need to do simple tests to determine some properties, such as how hard the mineral is. You can use a mineral's properties to determine its identity because the properties are determined by the chemical composition and crystal structure, or the way that the atoms are arranged.
