Answer 2

In diamond, each carbon atom is joined to four other carbon atoms. This gives diamond a hard three dimensional structure.

Whereas

In graphite, the weak forces between each plane if hexagons allow them to slide easily over one another. This makes graphite soft.

Two uses of graphite are-

• It is used for making pencil lead.
• It is used as a lubricant.
