\nD) Quartz
\n<\/section>\n
\nAllotropes are different structural modifications of an element in the same physical state.
\n– Graphene, Graphite, and Fullerene are all allotropes of carbon. Graphene is a single layer of carbon atoms in a hexagonal lattice. Graphite is composed of multiple layers of graphene stacked together. Fullerenes are carbon molecules forming hollow spheres, ellipsoids, or tubes (like buckyballs).
\n– Quartz, on the other hand, is a mineral composed of silicon and oxygen, with the chemical formula SiO2 (silicon dioxide). It is a major component of the Earth’s crust. Therefore, quartz is not a form of carbon.
\n<\/section>\n
\nOther common allotropes of carbon include diamond and amorphous carbon. The different physical properties of these allotropes (e.g., hardness, conductivity) are due to the different ways the carbon atoms are bonded together.
