1) What is allotropy? What is the difference between allotropy and polymorphism?

2) How does the differences in the structures of carbons affects their mechanical properties,

density, electrical properties, optical properties, etc.?

3) What are the applications of carbon and graphite based on the properties you described earlier?

4) Name some of the other allotropes of carbon. How their structures look like and what properties

they gain with these structure?

5) Using the information discussed in the post-discussion, fill in the table below.
