WebApr 10, 2024 · Answer In a compound X Y 2 O 4 , oxide ions are arranged in CCP and cations X are present in octahedral voids. Cations Y are equally distributed between octahedral and tetrahedral voids. Cations Y are equally distributed between octahedral and tetrahedral voids. The fraction of the octahedral voids occupied is: (A) 1 / 2 (B) 1 / 4 (C) 1 / 8 WebThe number of other particles that each particle in a crystalline solid contacts is known as its coordination number. For a polonium atom in a simple cubic array, the coordination number is, therefore, six. Figure 3. An atom in a simple cubic lattice structure contacts six other atoms, so it has a coordination number of six.
