Quartz consists of ______.
Silicon
The correct answer is Silicon.
In quartz, these tetrahedra are linked together in a way that shares all four oxygen atoms, forming a stable, three-dimensional framework. This structure gives quartz its hardness and resistance to weathering. Quartz can exist in various forms, including crystalline quartz (like amethyst, citrine, smoky quartz, rose quartz) and microcrystalline or cryptocrystalline varieties (like chalcedony, agate, jasper). Despite the variations in appearance, the fundamental chemical composition remains silicon dioxide ( \text{SiO}_2 ).
