Question

1. the table above does not show all of the uses for the minerals listed. through your own research or personal knowledge, find one additional use for 2 of the minerals above. for example (and you cannot use this one!), copper is also used to make pipes. 4. diamond and graphite both have the same chemical composition. they are both made entirely of carbon. based on this fact and the uses shown in the table, what can you conclude about the importance of the arrangement of the atoms?

Explanation:

1. For example, quartz is used in making glass. Mica is used in electrical insulators.
2. Since diamond and graphite have the same chemical - composition but different uses (diamond is hard and used in cutting tools, graphite is soft and used in pencils), the arrangement of atoms greatly affects the physical properties and thus the uses of a substance. The same elements can have very different characteristics based on how their atoms are arranged.

Answer:

1. Quartz - used in making glass; Mica - used in electrical insulators
2. The arrangement of atoms greatly affects the physical properties and uses of a substance.
