    In a solid AB having NaCI structure, atom A occupy the comers of cubic unit cell. If all the atoms along one of the body diagonal axis are removed then resultant stoichiometry of the solid is

    A)  \[A{{B}_{2}}\]                                  

    B)  \[{{A}_{2}}B\]

    C)  \[{{A}_{2}}{{B}_{3}}\]                                   

    D)  \[{{A}_{5}}{{B}_{4}}\]

    Correct Answer: D

    Solution :

    Effective no. of atom A/unit cell = 5 Effective no. of atom B/unit cell = 4
