In a compound oxide ions are arranged in ccp
WebThere are two tetrahedral holes for each anion in a CCP array of anions. A compound that crystallizes in a closest-packed array of anions with cations in the tetrahedral holes can have a maximum cation:anion ratio of 2:1; all of the tetrahedral holes are filled at this ratio.

WebNov 13, 2024 · If we take into consideration the actual sizes of the ions (Na + = 116 pm, Cl – = 167 pm), it is apparent that neither ion will fit into the octahedral holes with a CCP lattice composed of the other ion, so the actual structure of NaCl is somewhat expanded beyond the close-packed model. WebJul 19, 2024 · In a normal spinel type structure, the oxide ions are arranged in ccp, whereas, 1/8 tetrahedral holes are occupied by Zn2+ ions and 50% of octahedral holes are occupied …
WebMetals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous solids. For examples, candle waxes are amorphous solids composed of large hydrocarbon molecules. Some substances, such as silicon dioxide (shown in ... WebSolution. The correct option is B 1/2. In P Q2O4, oxide ions are arranged in ccp lattice. We know, ccp lattice has a face centred unit cell. Therefore, the number of particles present in …
WebWhat is the formula of compound. ... Q.5 Spinel is a important class of oxides consisting of two types of metal ions with the oxide ions arranged in CCP pattern. The normal spinel has one-eight of the tetrahedral holes occupied by one type of metal ion and one half of the octahedral hole occupied by another type of metal ion. WebAccording to formula MgAl2O4 oxygen contains 4 atoms that means it is forming CCP or FCC also there is only 1 mg atom and 2 Al atom.Z=4Octahedral voids=4Tetrahedral voids=8As mg is occupying tetrahedral voids so percentage = (1/8)×100=12.5%.And percentage of octahedral voids occupied by Al atoms= (2/4)×100=50%.
