How do polymorphs of carbon differ in terms of their physical and chemical properties?

Polymorphs of carbon, such as diamond and graphite, differ in their physical and chemical properties due to their different atomic arrangements. Diamond is hard, transparent, and has a high melting point, while graphite is soft, opaque, and has a lower melting point. Additionally, diamond is a poor conductor of electricity, while graphite is a good conductor. These differences arise from the unique bonding structures of each polymorph.
