What is zinc blende?
Zinc blende, also known as sphalerite, is a mineral composed primarily of zinc sulfide (ZnS). It is characterized by its isometric crystal system and typically exhibits a range of colors, including yellow, brown, and black, depending on impurities. Zinc blende is the primary ore of zinc and is significant in the mining industry for extracting this metal. Its crystal structure is notable for its tetrahedral coordination of zinc and sulfur ions.
Dose malachite have a crystal structure?
Yes, the mineral malachite does have a crystal structure.
What is the crystal structure of phosphorous?
The crystal structure of phosphorous is monoclinic.
Why the lattice parameter increase with zinc concentration?
The increase in lattice parameter with zinc concentration in alloys, such as in the case of brass, is primarily due to the larger atomic radius of zinc compared to other metals like copper. As zinc atoms are introduced into the crystal lattice, they occupy interstitial or substitutional sites, causing an expansion of the lattice structure. This results in an overall increase in the lattice parameter as the crystal accommodates the larger zinc atoms. Additionally, the differences in bonding characteristics between the constituent elements can also contribute to this expansion.
How does adding zinc affect the melting point of the copper?
Adding zinc to copper forms an alloy known as brass, which typically has a lower melting point than pure copper. The presence of zinc disrupts the copper's crystal lattice structure, making it easier to melt. As a result, the melting point of the copper-zinc alloy can be significantly lower than that of pure copper, depending on the zinc content. This property is beneficial in various applications where lower melting points are advantageous for casting and shaping.
Bravais lattice structure of diamond and zinc blend?
According to Wikipedia: The mineral sphalerite... "crystallizes in the cubic crystal system. In the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated. The structure is closely related to the structure of diamond." You can read more about Bravais lattaice by following the link, below.
Name the type of point defect that occurs in a crystal of zinc sulphide?
A common type of point defect that occurs in a crystal of zinc sulphide is a vacancy defect. In this defect, an atom is missing from its lattice position, creating a gap or a vacancy in the crystal structure.

Is zinc an example of pure metal with a hexagonal close-packed arragements?
Yes, zinc is a pure metal that adopts a hexagonal close-packed (HCP) crystal structure at room temperature. In its solid form, zinc atoms are arranged in a close-packed hexagonal lattice structure, making it an example of a pure metal with HCP arrangements.
How many sulfur ions are joined to each zinc ions in the compound zinc sulfide?
