A) \[{{X}_{2}}Y\]
B) \[{{X}_{3}}Y\]
C) \[X{{Y}_{2}}\]
D) \[X{{Y}_{3}}\]
Correct Answer: D
Solution :
X atoms are at eight corners of the cube. Therefore, the number of X atoms in the unit cell \[=\frac{8}{8}=1\]. Y atoms are at the face centre of six faces. Therefore, its share in the unit cell \[=\frac{6}{2}=3\]. The formula is \[X{{Y}_{3}}\].You need to login to perform this action.
