In a solid $‘ A B ’$ having the $N a C l$ structure, $‘ A ’$ atoms occupy the corners of the cubic unit cell. If all the face centered atoms along one of the axes are removed, then the resultant stoichiometry of the solid is:

Options:

Answer:

Solution:

$A = \frac{1}{8} \times 8 (corner) + \frac{1}{2} \times 4 (faces) = 3$
$B = 1 (centre) + \frac{1}{4} \times 12 (edge) = 4$
$A_{3} B_{4}$
