Answer:

1.diamond, graphite, and fullerenes.

2.a material produced by the incomplete combustion of heavy petroleum/ink for printing newspapers, as ink-jet toner, and coloring leather in shoes

3.Diamond is extremely hard while graphite is pretty soft, diamond has a greater density than graphite, and diamond is semi transparent while graphite is dark and foggy

4.Graphite can conduct electricity because of the free electrons in its structure. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised(free) electrons.
