Vedclass · Answer

(B) The structure of $MgO$ is similar to $NaCl$ (rock salt structure). In the $NaCl$ crystal lattice,both the cation $(Na^+)$ and the anion $(Cl^-)$ occupy octahedral voids. Since $MgO$ follows the same structure,the $Mg^{2+}$ ions occupy octahedral voids,and the $O^{2-}$ ions form a face-centered cubic $(fcc)$ lattice. The coordination number of an ion in an octahedral void is $6$. Therefore,the coordination number of $Mg^{2+}$ is $6$.

The structure of $MgO$ is similar to that of $NaCl$. What is the coordination number of $Mg^{2+}$?
