$Na_2O$

Vedclass · Answer

(A) The antifluorite structure is characteristic of compounds with the formula $A_2B$,where the anions $(B^{2-})$ form a face-centered cubic $(fcc)$ lattice and the cations $(A^+)$ occupy all the tetrahedral voids.Among the given options,$Na_2O$ follows the $A_2B$ stoichiometry,where $Na^+$ ions occupy all tetrahedral voids and $O^{2-}$ ions form an $fcc$ lattice.Therefore,the correct option is $(A)$.
