Which element is in both graphite and diamond?

helium

carbon

nitrogen

lithium

Carbon is present in both diamond and graphite.

The allotropes of carbon are called as Graphite and diamond. These minerals synthetically comprise of carbon molecules with various physical properties. These minerals, when all in options, are referred to be as polymorphs, having a similar kind of science, however of the different crystalline structures.  

In these allotropes of carbon, the molecules comprising of carbon atoms in that of the Diamond and Graphite, are bound together by solid covalent bonds with various courses of action.  

Valuable stone and graphite have move structures which speak to their assorted properties, and both are unadulterated carbon. In any case, the graphite's particles join to the three atoms of carbon and get related with the plates that are parallel to one another. The particles of Diamond enter the four atoms of carbon in an outline.
