    Sodium has body centred packing. Distance between two nearest atoms is \[3.7\,\overset{\text{o}}{\mathop{\text{A}}}\,\]. The lattice parameter is

    A) \[6.8\,\overset{\text{o}}{\mathop{\text{A}}}\,\]                            

    B) \[4.3\,\overset{\text{o}}{\mathop{\text{A}}}\,\]            

    C)                        \[3.0\,\overset{\text{o}}{\mathop{\text{A}}}\,\]           

    D)        \[8.6\,\overset{\text{o}}{\mathop{\text{A}}}\,\]

    Correct Answer: B

    Solution :

    Neighbour distance of a body centred cubic cell \[\frac{C}{3},\frac{V}{3}\] where a is the lattice parameter. \[3C,\frac{V}{3}\]\[\frac{V}{3},3V\]or\[3C,3V\]
