Info about 3 allotropes of carbon
Answers
Explanation:
Diamond
A diamond is one giant molecule of carbon atoms. Diamonds are colourless and transparent. They sparkle and reflect light, which is why they are described as lustrous. These properties make them desirable in items of jewellery.

Diamond is extremely hard and has a high melting point.
Graphite
Graphite contains layers of carbon atoms.

Graphite is black, shiny and opaque. It is not transparent. It is also a very slippery material. It is used in pencil leads because layers easily slide onto the paper, leaving a black mark. It is a component of many lubricants, for example bicycle chain oil.
Graphite is insoluble in water.
Nanotubes
Nanotubes are a type of fullerene and are molecular-scale tubes of carbon arranged similarly to the layers in graphite.
