Answer 2

Allotropes

They are framed so the carbon molecules fit into octahedral interstices in a nearby pressed metal cross section when the metal particle's sweep is more noteworthy than ~135 pm.  

Middle Transition Metal Carbides  

In middle change metal carbides, the progress metal particle is littler than the basic 135 pm, and the structures are not interstitial but rather are progressively perplexing. Various stoichiometries are normal. For instance, iron structures various carbides: Fe3C, Fe7C3 and Fe2C.

Aluminum structures carbides, yet different components from bunch XIII don't. These materials have disconnected carbon focuses, regularly depicted as "C4-" in the metanides, "C22-" in the acetylides, and "C34-" in the sesquicarbides.

Precious stone is straightforward, a definitive grating, and can be an electrical protector and warm transmitter. On the other hand, graphite is dark, a generally excellent ointment, a great channel of power, and a warm protector.
