WebApr 12, 2024 · In ionic solids, this generally means the anions, which are usually arranged in a simple cubic, bcc, fcc, or hcp lattice. Often, however, the anion lattices are not truly “close packed”; because the cations are large enough to prop them apart somewhat, the anions are not actually in contact with one another. WebApr 5, 2024 · Answer: The probable formula of the compound is . Explanation: Let the number of atoms in CCP arrangement be n Number of tetrahedral voids in CCP = 2n Number of octahedral voids in CCP = n number of oxide ion = n If 1/6 of the tetrahedral voids are occupied by atom A. Number A atom = If 1/3 of the octahedral voids are occupied by …
