A) \[{{A}_{2}}{{B}_{2}}\]
B) \[A{{B}_{3}}\]
C) AB
D) \[{{A}_{3}}B\]
Correct Answer: B
Solution :
A atoms are at the corners of a cube. So, the number of A atoms per unit cell \[=8\times \frac{1}{8}=1\] Similarly, B atoms are present at face centres of a cube. So, the number of B atoms per unit cell \[=6\times \frac{1}{2}=3\] Hence, the compound is \[A{{B}_{3}}\].
