Question
Sodium oxide has anti-fluorite structure. The percentage of the tetrahedral voids occupied by the sodium ions is
Answer: D
💡 Solution & Explanation
In the anti-fluorite structure (Na$_2$O), oxide ions (O$^{2-}$) form the CCP lattice and sodium ions (Na$^+$) occupy all of the tetrahedral voids. Hence, 100% of the tetrahedral voids are occupied. Therefore, correct answer is D.
