Concept explainers
(a)
Interpretation:
The packing of sulfur ions should be determined.
Concept introduction:
The elements or substances exist more in solid than liquid and gases. These solids can be two types amorphous and crystalline. The crystalline solids are solids that contain their constituent particle in arranged manner. While amorphous solids are solid in which constituent particles get arranged randomly such as rubber.
The packing of these solids can be four types, simple cubic, body-centered cubic, hexagonal closest-packing, and cubic closest-pacing.
(b)
Interpretation:
The total number of sulfur ions and zinc ion in given unit cell should be determined.
