In NaO structure — Solid State Chemistry Question
Question
In Na$_2$O structure
Answer: B
💡 Solution & Explanation
Na$_2$O crystallizes in the anti-fluorite structure. In this arrangement, the larger anions (O$^{2-}$) form a cubic close-packed (CCP) lattice and the smaller cations (Na$^+$) occupy all of the tetrahedral holes. Therefore, correct answer is B.
