• # question_answer Element 'B' forms $ccp$ structure and 'A' occupies half the octahedral voids, while oxygen atoms occupy the tetrahedral voids. The structure of bimetallic oxide is: A) ${{A}_{2}}B{{O}_{4}}$                     B) ${{A}_{4}}{{B}_{2}}O$ C) $A{{B}_{2}}{{O}_{4}}$         D) ${{A}_{2}}{{B}_{2}}O$.

\begin{align} & \begin{matrix} A & : & B & : & O \\ \frac{1}{2}(O.V.) & : & CCP & : & all\,T.V. \\ \end{matrix} \\ & \frac{4}{2}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,4\,\,\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,\,8 \\ & 2\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,\,4\,\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,\,\,8 \\ & 1\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,\,\,2\,\,\,\,\,\,\,\,:\,\,\,\,\,\,\,\,\,\,\,4 \\ \end{align} $A{{B}_{2}}{{O}_{4}}.$
